mac addies

Has anyone looked into using mac addresses in the identification process
for OS fingerprinting? It might sound weird but knowing that the nic in
the computer is made by Unisys or cray or whatever else, can help narrow
down the number of choices? 
 
I don't know just a thought, it seems too complex to mess with but I
thought I'd share anyway
