And if you try to connect using a MAC address currently in use by another
customer, what happens? If you appear to be an already known customer
(previously seen MAC address), will it assign the same IP address, will it
declare that IP address in use and assign another address, or wilt it declare an
unidentified problem and maybe disconnect both instances of the same MAC
address?
