I think Seti@home is a good idea. I think if people are not using their Speed Deamon Computers, then they should Help out the Seti Searchers with their computers.
SETI@home and Astropulse are funded by grants from the National Science Foundation, NASA, and donations from SETI@home volunteers. AstroPulse is funded in part by the NSF through grant AST-0307956.
