It seems like there is potential for a much bigger market than games. Streaming video and audio... fantasy sport applets, etc. Is plura just starting with games since they provide what I suspect are ideal conditions (already using CPU and running long enough to for Plura to actually do some work).
There is a big search in the gaming industry for new sources of revenue. Development costs are skyrocketing but income is not. Retail and subscription are the big two, with online advertisements growing in popularity. If harnessing players' compute time enables a gaming service provider to offer a better product at a lower price, this could be a win for the gamer, the game company, and the ultimate computing consumer.
Yes, we are definitely interested in other sites too. Our main page is pretty generic, but we decided to do a special pitch to game developers for exactly the reasons you state.
