I really think that "bluetooth" serial or "direct audio connections" create a 
lot of limitations on what is achievable.  Look at the WiSnap or other "WiFi" 
interfaced serial port devices.  If you focus on that style interface, then 
interacting with that device vs an i-Gate is nearly zero.  This means that you 
can decide when you are "on the air".  If you carry around a small access point 
for use in your vehicle, you can even take you APRS device out of your vehicle 
and use it remotely.

This is the model of design that I've used on my APRSNow application for the 
iPad.  I still don't have a WiSnap connected to mine, but as soon as my current 
financial situation improves, I will probably put a MacMini in the car and use 
it's WiFi to connect through to a USB-Serial dongle served by a JavAPRSsrv 
instance which will also have my Verizon USB Cellular modem attached when I need 
a full internet connection.  That will let me park near a support event, get out 
with my iPad, and do APRS and access the internet both.
