1) when your primary machine is an XP/2K box running ICS, is that illegal 
also? Are we to expect comcast to come knocking at the door wanting to 
inspect the configuration of our PCs to see if it has 2 NICs, or a 
wireless card in it? Are we supposed to willingly just open up our PCs so 
comcast can look inside?

2) I heard recently of ppl openly sharing their broadband connection using 
802.11 access points, Airports etc among friends, neighbors, coworkers.  I 
can see where your DSL or cable company would be a little more concerned 
about losing revenue like this, over just 2 or 3 PCs sharing at one 
domestic location.
