I've been working on a piece of software for about 3 years now, that would allow you to get a 24/7 server completely free in exchange for donating you're PC to a pool of computers for a certain quota a month (e.g. 4h a month). Before I complete the final stages, I would love to know if anybody would be interested in a service like this? If you are, you may be able to get alpha and beta access to the software before it launches by posting "I would be interested" and/or any other questions.
How did you get on?
