Ok, after thinking about it for a while I have decided that I very much like
the SLIP over UART strategy as a place to start.  An aspect of this that really
caught my attention was the ability to plug the I/O hardware into a PC for
development purposes and then plug it into the target embedded system for
deployment.  In my opinion this is an absolutely brilliant concept!

Also, it seems that both you and Gregg had similar strategies for implementing
peer-to-peer on top of a master/slave architecture and this seems to be an
excellent idea which addresses a number of concerns that I had with
master/slave hardware.
