I am curious to know if anyone has CCA deployed with any CAS configured for
out-of-band.

After reading the documentation it is clear that OOB is quite more involved
than in-band.  I'd like to know if anyone has had many problems arise from
doing things this way.  It seems obvious that quite a bit more planing would
be required on the network side.  If anyone has experience with configuring
OOB please post here, I'd like to start a discussion.

OOB is what is being suggested to us (for actual implimentation) from the
security firm assisting us with our pilot.  Currently I have only been
playing with in-band in the test environment.
