sensor nets anyone?
The bridge-monitoring stuff sounds a lot like SCADA.

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".
I've heard tha's pretty close to how IPv6 ends up being used as far as current public production installation use go (not counting those done for research, etc). For example apparently some railroad in europe setup ipv6 for use in the rail sensors. Then we also recently heard of large ISP using ipv6 for creating management subnet for all their network equipment, etc. -- William Leibzon Elan Networks william@elan.net
