Here's a new twist on an old thread.

Rather than require that each piece of hardware be customized to some new protocol, how about using something like this:http://www.linux-usb.org/USB-guide/x356.html

With a supported piece of hardware, this would let you connect up many unmodified serial devices (GPS reciever, OBD-II adapter, laptop, etc) while still leaving the built-in serial port free for connection to a Sony (or other brand) stalk.

I guess the real question is: can we convince mlord to add module support to hijack?
(the other modules I'd like to load are IrCOMM and IrOBEX drivers)
