sensor nets anyone?
The bridge-monitoring stuff sounds a lot like SCADA. //drift IIRC, someone representing the electrical companies approached someone representing network providers, possibly the IETF, to ask about the feasibility of using IP to monitor the electrical meters throughout the US. Presumably this would be via some slow signalling protocol over the power lines themselves (slow so that you don't trash the entire spectrum by signalling in the range where power lines are good antennas - i.e. 30MHz or so). The response was "yeah, well, maybe with IPv6". -- ``Unthinking respect for authority is the greatest enemy of truth.'' -- Albert Einstein -><- <URL:http://www.subspacefield.org/~travis/>
