[Cialug] Mediacom and Qwest IPs

[Josh More]

It's never going to be perfect, we know.  There are mitigating factors
that I cannot discuss on a public list.  We're really just going for
something that provides real security with a minimal interruption to
operations.  It's a difficult balance, but it should be possible if we
accept a somewhat fuzzy definition of "done".

Luckily, wireless is not a consideration for this one.  (whew!)

I hope you're charging this client an nice hourly rate becuase this is
going to be a difficult, if not impossible task.  (Personally I'd say
it's pointless, but it's their money I guess).

Don't forget about "ISPs" like the ICN, U of I, and Iowa State.

And what about wireless providers like Verizon, US Cellular, etc.?

Might be worth looking into the various geolocation databases out there.
