I know what you are thinking, lag lag lag, but there are possible ways to use a computer to render games for another pc, given you know what you are doing I think it could be possible.
Heres a great example "StreamMYGame" allows you to stream games from PC to PS3. Another would be remote play for psp, you can actually play some ps3 games using it(yes).
The service would be cheap at $4/hour?
People could buy credits and rent out a pc of their choice, look at the specs, the locations, ping time ms, and more.
If this idea is favored and i'm not hated for trying to be creative, I can program it.
Edit: I'm going to try and experiment on making a free alternative to streammygame, any help would be appreciated greatly.
Double Edit: Just made a remote desktop app by sending pics over tcp(was gonna do udp but was rushing). And it's way to laggy to be used for anything other than remote desktop help .
