I would not just use one Mac Address, while the majority of the

Apple computers and Base Stations
Really? Although MACs are assigned in a unique fashion to businesses,
some NICs allow to change them.
If this is really true, TCP/IP's ARP protocol will break. So the
systems might not be used in one network. Hm...
You can do this quite easily on many NICS, and in OS X it's easy to do
as well.
And what about if the user changes the order of network devices in
System Preferences, wouldn't this then reflect in the RB code?
This is a problem. Moreover, not all NIC are enabled all the time.
On another side note, the serial number of the Mac is stored on the
Hard Drive, so if you swap Hard Drives or reformat it, it may not
have the serial number. I personally have partitioned my drive and
now my machine does not have a serial number [except the one printed
on the underside].
Isn't the serial stored somewhere in PRAM and thus assumed to be
constant?
No. Set on the hard drive and if you appropriately wipe the HD you can
nuke this.
Not in PRAM as that would add too much to the overall manufacturing
process.
