I think that SETI@home is probably humanity's best opportunity to find intelligent extraterrestrial life. I feel that humans should not transmit a beacon to others (even though we already do).
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.
