Not on Mac, but the simple version is. C5 on main pc then render nodes on the others. Make sure to include all the plugins on render nodes. Check the port options also under prefs. Don't forget ot enable network rendering in render room. There is some info on this in the docs. Wireless will work. Wireless is not as fault tolerant as cable so yes there can be issues introduced, but as long as you have a reliable connection with good thoroughput it should be fine.

No need to think outside the box....
    Just make it invisible.
