okay, after speaking with a few people this is what I have come up with, based on their advise

These shaders are provided free of charge for use in ANY PERSONAL RENDER, they are NOT to be used in or given away in ANY COMMERCIAL product in anyway, be it for yourself (own product) or a 3rd party (product and or promotion), they are not allowed to be used in part full, or any fraction thereof in a MERCHANT resource, on the front of a magazine, and/or freebie disc, DVD or any electronic means known or unknown.

What this means is that you are free to use them for any personal render you do, if you wish to enter it in a compition where money many be won, that isn't classed as commerical and you are free to use them in that.

Hope this has cleared things up for you

Not sure how Hivewire do it, but I am new to this, and this is the way I think I should go based on the advise I have been given :)
