One of the main driving forces behind my efforts is to reduce the number of
support phone calls, by significantly reducing the complexity of getting a 
up and running.

Expect is Linux specific. I want to be able to do things using
tools as simple as Hyperterminal, or even without serial line at all.

If  you, like me, dont deliver any boards, then you do not have this 
It is the reponsibility of the user of the S/W to ensure that it is
used in a restricted environment like production or development
where the MAC address can be selected at random.
