Several companies have gotten in trouble with things like that. Not sure which company it was but one of the graphic companies put a no "porno" use in their agreement and it was shot down. The thing to remember with EULA's is that they cannot go against the Fair Use laws. taken from : http://www.cetus.org/fair5.html The Fair-Use Statute The following is the full text of the fair-use statute from the U.S. Copyright Act. Section 107 of the Copyright Act of 1976. Limitations on exclusive rights: Fair use Notwithstanding the provisions of sections 106 and 106A, the fair use of a copyrighted work, including such use by reproduction in copies or phonorecords or by any other means specified in that section, for purposes such as criticism, comment, news reporting, teaching (including multiple copies for classroom use), scholarship, or research, is not an infringement of copyright. In determining whether the use made of a work in any particular case is a fair use the factors to be considered shall include -- 1. the purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes; 2. the nature of the copyrighted work; 3. the amount and substantiality of the portion used in relation to the copyrighted work as a whole; and 4. the effect of the use upon the potential market for or value of the copyrighted work. The fact that a work is unpublished shall not itself bar a finding of fair use if such finding is made upon consideration of all the above factors. (Emphasis added) The Meaning of the Four Factors While fair use is intended to apply to teaching, research, and other such activities, a crucial point is that an educational purpose alone does not make a use fair. The purpose of the use is, in fact, only one of four factors that users must analyze in order to conclude whether or not an activity is lawful. Moreover, each of the factors is subject to interpretation as courts struggle to make sense of the law. Some interpretations, and their subsequent reconstruction by policy-makers and interest groups, have been especially problematic. For example, some copyright analysts have concluded that if a work being used is a commercial product, the "nature" factor weighs against fair use. By that measure, no clip from a feature film or copy from a trade book could survive that fair-use factor. Similarly, some commentators argue that if a license for the intended use is available from the copyright owner, the action will directly conflict with the market for licensing the original. Thus, the availability of a license will itself tip the "effect" factor against fair use. Neither of these simplistic constructions of fair use is a valid generalization, yet they are rooted in some truths under limited circumstances. Only one conclusion about the four factors is reliable: each situation must be evaluated in light of the specific facts presented. The fair Use statue from the US. Copyright website (http://www.copyright.gov/fls/fairuse.html) Fair Use One of the rights accorded to the owner of copyright is the right to reproduce or to authorize others to reproduce the work in copies or phonorecords. This right is subject to certain limitations found in sections 107 through 118 of the copyright act (title 17, U.S. Code). One of the more important limitations is the doctrine of fair use. Although fair use was not mentioned in the previous copyright law, the doctrine has developed through a substantial number of court decisions over the years. This doctrine has been codified in section 107 of the copyright law. Section 107 contains a list of the various purposes for which the reproduction of a particular work may be considered fair, such as criticism, comment, news reporting, teaching, scholarship, and research. Section 107 also sets out four factors to be considered in determining whether or not a particular use is fair: 1. the purpose and character of the use, including whether such use is of commercial nature or is for nonprofit educational purposes; 2. the nature of the copyrighted work; 3. amount and substantiality of the portion used in relation to the copyrighted work as a whole; and 4. the effect of the use upon the potential market for or value of the copyrighted work. The distinction between fair use and infringement may be unclear and not easily defined. There is no specific number of words, lines, or notes that may safely be taken without permission. Acknowledging the source of the copyrighted material does not substitute for obtaining permission. The 1961 Report of the Register of Copyrights on the General Revision of the U.S. Copyright Law cites examples of activities that courts have regarded as fair use: quotation of excerpts in a review or criticism for purposes of illustration or comment; quotation of short passages in a scholarly or technical work, for illustration or clarification of the authors observations; use in a parody of some of the content of the work parodied; summary of an address or article, with brief quotations, in a news report; reproduction by a library of a portion of a work to replace part of a damaged copy; reproduction by a teacher or student of a small part of a work to illustrate a lesson; reproduction of a work in legislative or judicial proceedings or reports; incidental and fortuitous reproduction, in a newsreel or broadcast, of a work located in the scene of an event being reported. Copyright protects the particular way an author has expressed himself; it does not extend to any ideas, systems, or factual information conveyed in the work. The safest course is always to get permission from the copyright owner before using copyrighted material. The Copyright Office cannot give this permission. When it is impracticable to obtain permission, use of copyrighted material should be avoided unless the doctrine of fair use would clearly apply to the situation. The Copyright Office can neither determine if a certain use may be considered fair nor advise on possible copyright violations. If there is any doubt, it is advisable to consult an attorney. Fair use though is one of those things that you have to go to court over to find out if you or the owner is right. Not a lot of people want to test that. A liscense is the legal mumbo jumbo of a agreement an eula is the fair use of that product. I have seen a lot of people violating the fair use statute, Especially in the poser community. Basically what it boils down to is I can tell you what not to do within reasonable limits. Such as redistributing and warezing. I can tell you you can only put it on 1 computer at a time. But I cannot limit your use of the item (ie I can't release a character and tell you you can't do porno with her, I cannot tell you that if you buy my software that you cannot sell it to your friend for 10 bucks. I can't tell you that you can't give it as a gift to a friend) I Can however tell you that you cannot duplicate that software and sell it to 50 friends.
