Hi Adam,

Another variation on your idea is to use Snort to detect spyware type
packets and drop those packets.  This can also be used to limit virii
from overloading your network connection (it doesn't protect computers
on your LAN however).  ClarkConnect (I'm sorry if I always seem to be
"plugging" CC) has plans to do something like this.

The basis for the CC implementation is http://www.bleedingsnort.com if 
you want to "roll your own".

Hope this helps.
