I strongly believe that there's more in space than we know at this moment. The reason why I'm running SETI@HOME is because I think it is important to use all of the resources available to hunt for other ETI.
It is a pitty I did not hear about this great project earlier!!! If we should transmit a beacon for others to find, it should contain the movie "Close Encounters of the Third Kind" ;-D)
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.
