Around here, if the cable company did that, they'd lose lots of 
customers.  Texas A&M has a VPN setup so that students, 
faculty, and staff can access the campus network better.  Some of 
the network is available without it, but some of it cannot be 
accessed from off campus without the VPN.  I also frequently run a 
second VPN connection to a private company for work purposes.

The local cable company has recognized that if they actually try to 
enforce certain provisions of the AUP, they're going to have 
problems with their customers.

For instance, they assert that servers are not allowed.  What they 
really want is no high bandwidth servers available to the general 
public.  But they have acknowledged that we can run servers for 
our own personal use.  When I subscribed to the service, I pointed 
out that I run quite a few services from my computer and they never 
had a problem with that.  

For instance, I run www, ftp, smtp, pop3, dns, and syslog services 
as well as anything I may be developing and told them so. Most of 
these allow connections from selected ip addresses or blocks only, 
so it would be difficult for them to actually check some of them.
