I run Seti because I was interested in the use of distributed processing and the thought of computers around the world used for a common goal was an interesting concept.
With the current level of hardware and software I thing the probability of finding signals from anything other than natural sources is small.
Don't give up, modern communications started with humble beginnings from Bell and Marconi.
