Grid computing is not new, I participate in this (or some very similar project) through Grid.org. I watch proteins folding and whatever analysis is done on them on my screensaver all the time. My old computer takes the better part of a week to finish one block, but so what?

I have no problem with this because I know what the program is doing, I can configure it to use only certain ports and allow those through my firewall. I can help research without any real cost to me. All I need to do is leave the computer run all the time (I do anyway) and let it connect to the Internet at will. Simple enough.

Others may have a different opinion though.
