Unfortuantely there are enough protocols and applications
which don't work well behind a NAT that deploying this on
a large scale is not practical.  Most gamers require incoming
connections.  These are people who willing to pay for bandwidth
so attempting to put them in the "nat only" box will not work.
Also what about folks who need to VPN in to their office
(either via PPTP or IPSEC)?  How would you take care of that
situation?

Unfortunately something like this would make the PC close to
useless which is not the intent of the software provider.  Thus
you see everything open, security be damned.

And there lies your problem (among other places)....
