mmm okay... so say that theres this fictitious big cable tv provider... hehe... and this customer wants to divide that big fat 1.5MB pipeline amongst a desktop for f/t use and a laptop for p/t use... and the customer realizes that you need to have the same MAC address to get an IP address on the provider's network. Could the customer theoretically throw up a router that has a configurable MAC address... and solve everything? And who would make such a product?
