SRTP for Asterisk is "ready for testing", though the last active 
patch submitter stated that he needed to get a new patch about a 
month ago and there has been no activity there since.

To morph this into a -dev thread: if this patch were to become 
(again) useful and error-free, is there any objection or usefulness 
in adding it to TRUNK?  Personally, I think there is, if there is a 
method by which SRTP can be activated or de-activated from within the 
dialplan based on prior shared secrets.  However, I have heard others 
disagree and object that without signalling-based secure key 
exchange, SRTP is not worth the effort.  Opinions?
