SETI is a very cool program... I think it's ahead of it's time. The Seti@home aplication is a good way to stay ontop of things, and every one help that want's to.
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.
