...unless they look at things like User-Agent: and X-Mailer: strings,
cookie handling, TCP sequence numbers, packet padding content, and other
clues that different OSes and applications provide. For instance, this
mail message probably has
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.5)
Gecko/20031007
somewhere in its headers.
There are products geared toward service providers that use passive
fingerprinting to detect multiple users on the same connection. Dunno
if TWC uses them.
IMO service providers should be happy when people put their stuff behind
a NAT device, even if they do use a little more bandwidth. A couple of
computers protected behind a SOHO firewall will cause far fewer
bandwidth headaches than a single virus/spam vector sitting directly on
an exposed connection.
