Except that you need a cable modem that's set up to put go into promiscuous mode, and not transmit anything.  I believe 
this may be doable with SNMP, but you would have to know the community strings used by the ISP.

The modems the ISPs ship only pass inward traffic destined for their own addresses.  I'm not sure if they announce 
their presence, if the computer behind them is silent - that might take some tweaking also.  What Alex described looked 
more like a passive tap, that won't emit any signals.
