Another problem with the Mac address is laptops, when the laptop is

on the train then Mac Address changes. Then the user gets home and

used
the Mac address to create a registration system in the past and I
encountered this many times and customers are none too pleased.
Uhhh... the MAC address shouldn't ever change. It isn't reliant on a
connection at all, it's a unique hardware identifier. A device's MAC
only
changes if it's changed by some spoofing software, or in the rare
case of
a BIOS configurable onboard. What you all are describing sounds more
like
the IP address, which is totally, radically different.
Agreed.
But if you use an active network interfaces MAC address derived from
one the RB methods it could seem to change as which device is in use
will change as you change from wireless to wired, etc
If you can access specific devices directly and not just via the RB
built in NetworkInterface class then you can probably be reasonably
assured that the MAC won't change (except when it does via the means
you listed etc)
