Doof_Guy and PHeMoX, he is offering payment so if there is an experienced programmer or modeller who has time to do it, he can contact Foamhead and will most probably get more information about the project and the payment. So the one working on it will know quite well what it is about without the idea being made public.
You should definatly post all the information if it is a free project but as well as payment is offered I don´t see a need for making everything public.

And sorry for beeing off topic, I just had to write this...

Edit: What you write in your post further down is right blade, but as you say, the worker has to "wow" his boss and not the other way around... The boss is usually the one who pays.
