A really interesting thing is happening here.  If you talk to
people who run enterprise networks and explain to them that 
through the use of firewalls and NATs they're interfering with
the ability to protect application traffic, they'll tell you
that they know that and it's part of why they do it.  They
perceive a need to put tight controls on what goes out of their
networks as well as what's permitted in, and it's not that
uncommon to find businesses that even require the use of company
proxies for outgoing ssh connections.  

End-to-end networking puts control into the hands of end users
and their applications.  The people who own the networks in
question may not, in many, many cases, think that's a good thing.
