The idea is to keep existing functionality such as TCP docking, and 
then add the ability to communicate to external hardware such as a 
Bluetooth dongle (well that also needs a Bluetooth stack :) ), or a 
modem, or whatever else you could hook up to the serial port on the 
host computer.

Matthias was also thinking to add a virtual dock, the way that would 
work is to add a serial port to Einstein which on the other end is 
connected to a Newton dock protocol implementation.

The REx driver is a bit easier to use for this as it does not need to 
emulate a full Voyager chip, but just regular I/O operations.
