Gao,

I still don't understand one aspect here:

Is this a case of
- a smart device with a limited display wanting to bring in
   a dumb device with a good display into an existing call?

- a smart device with a good diplay wanting to inject its
   capabilities into an existing call preempting a dumb
   device with limited capabilities?

- something else?

If its a smart device with limited display capabilities, I think it can 
just use 3pcc to control the device with the good display, as a slave 
media server to itself. In that case I think there are no unsolved issues.

	Thanks,
	Paul
