My apologies if this strays off topic, but I wanted to share my recent
experience.

We had a collocation customer come in and request a t1 of pots lines for
their servers, then complaints that their "security" software wasn't
working because of our RPF checks.  As it turns out they were dialing up
to a local isp, and sending bulk email using our bandwidth, but the
dial-up's ip.... And receiving the TCP ack on the dial up.  

Its not new. In fact, its so not new, I think those involved could quite
happily believe its very clever. :)
