SETI@home is great! While I think that the narrow band of frequencies being checked greatly narrows the possibility of finding any transmissions it is a great start. The sheer technical achievement of SETI@home is awesome.
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.
