Without a client being installed on the user's computer, tracking their
past history would be very difficult. I'm assuming that it is likely a
differen bus or train would service the same route at the same time on
different days. I don't reckon there would be that much regularity, but
that's just my humble opinion.

Block VOIP (and all other) traffic; allow only HTTP (and selected media
streams) via a proxy server.

I was envisaging (in part) a system where certain elements are free.
Something like the transit.tv system, but more interactive. So you could
view a few select (cached) websites for free, maybe watch the
re-broadcast TV signals, etc.

Except without the 15 minute lag, and a lot easier. Have a script at HQ
which tries to log into each box until it can, then propogates the
necessary changes. This should actually be easy unless any of the boxes
falls over, but that's what watchdog timers are for.

This is true, but I remember there being a shitfight over cable
companies re-broadcasting free-to-air signals. It got resolved, but it's
not quite as easy as you put it; Kerry Packer wants money, and he can
prevent you from broadcasting his signals unless you pay him.
