Actualy, there has been sidebar discussion here at Astricon (was it 
in session or in the hall or at dinner?  I have no idea.) about what 
to do for this.  Mark Vince and I have noted that this is is for some 
reason on everyone's midn, and possibly with the appropriate bribes 
or caffeine in the CodeZone it may get done, or at least discussed in 
more detail.  I would suggest that if anyone on the list who is not 
at Astricon has any code to contribute that this would be a great 
time to throw some ingredients in while the chefs are looking at this 
particular pot.

The problem set seems to be:
   - how do you [busy,un-busy] channels out from a "live" system without
       re-loading zaptel?  Should it be CLI only, or should there also be
       something that is possible from within the dialplan and/or AMI?
   - how do you display the status of channels?
   - how do you distinguish if the other side has busied a channel out?
