I totally agree with you on where the industry is headed and we will get
there.  Encryption has definitely become a MUST-HAVE with the technology
change to connectionless vs. timeslot-oriented network.  However, we are
not there yet.  Where there is a will, there is a way... on both sides of
the coin, unfortunately.

Although some individuals are just seeing the light, security is king, in
communications, and it has been for a long time.  I recall designing VSAT
systems for major corporations in the 80's, for both voice and data
applications.  Their #1 priority was encryption on both.  Along with this,
network isolation and ingress points MUST be key components to the design
of the deployment &/or service offering to protect both your customer and
YOUR network.

This has been a great discussion on a very important topic.
