There are universities who have set up 802.11 transmitters with range over 1km (dumb idea - shared bandwidth, anyone?) but I suspect the transmitter strength rules would be broken. Roger - I didnt have video in mind (although I know its been done in series past), but it would simplify the protocols for some telemetry. Theres no way I need 1Mbps, even for my dafter ideas. :-)

Out of interest, what do the house robots use for their cameras (assuming they dont record locally)?

Eddy - should be there, will look forward to chatting to you.
