you are right.  40+ years of rf experience from ham radio to broadcast to tactical ststems has taught me what works, what doesn't, and what will pi$$ off users.

it's your system.  do what you want.

So, along with that, keeping control codes somewhat masked (because the number of lids hasn't decreased) IS something that should be taken into accout. however specious that argument is (yeah, i know, listen on the input...).

DTMF doesn't propagate, since Asterisk THINKS the node is co-located with the compiter.  i have asterisk running at the remote site, btw.  i just use the core-to-remote frequency to control the far instance by writing scripts that do what i want, assigning them to a DTMF frequency, and so forth.
