looked at what I mentioned awhile ago and how feasible it is... and I'd
like to go further down that road!

channels. This operation would accept a direction for spying and a
direction for whispering. Of course "none" would be an option for both in
case you don't want to do them. This operation would internally create a
Snoop channel which snoops on another channel (oddly enough). Anything
written to it is whispered to the other channel (if a direction is
specified) and anything read from it is the spied audio (if a direction is
specified). The operation would also accept the name of a Stasis
application and optionally some arguments. The Snoop channel would be
placed into this app. The operation would return a snapshot of this Snoop
channel.

Stasis application you can do anything to it that can be done with a
channel. Monitoring becomes creating a snoop channel and calling record on
it. Whispering or live monitoring becomes creating a snoop channel,
creating a bridge, and putting another channel in the bridge. Whispering
media becomes creating a snoop channel and calling playback on it.

Sounds good to me, would you be able to change direction, or being able to
whisper etc etc part way through the channel's lifetime?

Still interested to see if you'd then be able to snoop and return an audio
stream via http but that's another issue
