Hi  Doug,  Sorry I cant help on you seismic shut off system
but I do express an interest in the the micro controller
with its own "IP" address and implements TCP/IP ++++.
I remember an article in "Dr. Dobbs" about a real-time
weather station made by a company called:
http://www.pharlap.com/

If you have more info on the manufactures address, that
would be great. Interesting possibilities. - good idea.

Regards
Arie
