I'm using blueyonder, and they have a selfcare webpage that lets you 
assign up to five mac addressess that can be used on the conection.

However you do need to reboot/power cycle the modem to force the modem
to check which mac address is in current use.

That's using a Surfboard SB4100 cable modem though
