I saw that thing once in which you 'donate' your PC's CPU while you're not using it in order to run simulations for cancer research.
Is there a way to do something like that with renders? Have a network of multiple computers to preform a render?
If so then: can you do it over the internet and what(how fast) internet connection do you need(how fast)?
do both computers need to have Maya installed?

(Won't it be awesome to have something like a P2P network with the members of this site or even bigger, for this purpose?)
Thanks in advance,
Benny
