@Matthew, @Marek:
Reading your messages again, I'm realizing having an accurate picture
of connected and disconnected devices will be a long and tough road,
in wireless world.
I'm looking for a way to prevent some users to resell WiFi access to
each other but probably not at the cost of severly degrading user
experience or flooding help desk.

My questions remain but maybe I should look for delayed analysis of
past records rather than a system relying on live ones.

Thank you very much for your inputs.
