                  but sucks if your cable or xDSL ISP decides NAT is the
way to go. (usually followed by a "well, you shouldn't need two or more
nodes there/want to run a server/care about SIP, a business should pay for
a DEDICATED link" for a little three-man sales office in the backend of
nowhere)

Or the road warrior case.  If you send 3 engineers to Detroit and they end up
at the wrong hotel.....

But regardless, all the workarounds are doing is trying to patch the fact
that UDP dependent connections are not NAT friendly by special-casing (or
app-layer proxying) particular instances of UDP in a way that doesn't drop
dead TOO often....

People are continually managing to make bears dance, and are surprised when
said bears decide it's time to voice their opinions on the matter....
