That's exactly what I was thinking about, since running the layer23 on the 
Application CPU is not a so good idea, it renders the phone usable only for a 
small period of time(since,in that configuration, you cannot suspend the AP 
CPU because it has to run the telephony code).

>maybe not the same as the infamous AT command interface
Why is AT bad? what other protocol do you propose?
