Astronomer by training, but have worked in building Internet-based electronic and information systems for the past 8 years after spending 10 years at Goddard Space Flight Center working for a NASA contractor. Got lots of machines in my consulting office running SETI@Home in their spare cycles.
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.
