You must be insane if you think an XML encoded event would be less 
overhead than a binary encoded event.  :)

Anyway, chan_iax2 would have extremely little processing to do on 
events.  They would be sent over the network in such a way that they can 
be directly passed into the event core and mapped to data structures.

Another argument for this generic event passing mechanism is for device 
state notification.  After I'm finished playing with message waiting 
indication, I am going to get device and extension state information 
converted over to this system.  Then, these states will be able to be 
shared between servers.  One phone will be able to subscribe to the 
state of a phone that is actually on another server.

It would be really nice for those of you working on IAX2 softphones to 
be able to support "buddy lists" with state monitoring natively in IAX2, 
wouldn't it?
