The MAC addresses that I ship are valid MAC addresses - it was that their 
DHCP server, only gave IP addresses to "valid" machines on their network 
(valid = machines that the net admin knew about and wanted on the network). 
Since they were hacking on this they did the best thing they could - they 
unplugged the Windows machine, and stole it's MAC address, so their DHCP 
server would give them an IP number that their routers liked.

OK - I guess that is what I was looking for. If I made a smc91111_eeprom.c, 
would you accept that back into the examples, and if someone wanted to 
change it, they could do it from there?

I guess I really didn't look in the examples dir. In the README, it says 
there are two simple examples - it didn't mention that there were complex 
ones to :)

This is the reason I asked before I started coding -
My five favorite words "architect, design, implement, test, ship".

Thanks for the pointers - I will see what I can get from the examples dir.
