connected to LAN

[Phil Davis]

Hey Jim,

Ideas:

- If the LANs serve different ranges of IP addresses via DHCP, then a 
laptop computer's IP address will indicate which LAN they are on.

- If they set up a different 'Location' on their machine for each 
network, you could probably detect the active one via system profiler. 
(On a Mac anyway)

That's all I can think of at the moment.
