If you have an nvidia card and you're mining litecoin, cudaminer (https://bitcointalk.org/index.php?topic=167229.0) is the way to go!

If it was possible to use that power at the same time to do things like that, yes it would be awesome. But if you're using that data to do it, there would always be people with access, and however good the intentions, where's there's people with access to information that can make you a lot of money.. someone will take that opportunity.
If you really want to help with calculations on different projects, get rich on coins and then buy dedicated hardware to help, can seldom have the best of both worlds.

Good job! Sucks that there's always people like that  I hope you can get something back from your investment.
