Got a machine on a connection elsewhere?

Decide you don't need your cable modem for a day (maybe you're out
of town), and dump your /dev/zero down an ssh socket forward to the
remote machine that's dumping the output of the socket into
/dev/null on its end. (Yes, you should be able to dd into and out of
a socket. If not, then Linux's dd implementation needs fixing.)

Use ethereal on the comcast end to measure bandwidth. Note that
it'll vary over the course of the day. If my previous second-hand
experience still holds, bandwidth will suck between 8am and 8pm and
rock during the other twelve hours.
