The situation you mentioned does not apply to the situation the OP was 
discussing and, as you mentioned, requires separate networks. This, of 
course, means the MAC is irrelevant to anything beyond the individual 
networks.  If you are outside of those networks, you don't even know 
what any of the MACs on those networks are and you don't care.

With my notebook computer, running OpenSUSE 12.1, if there are both 
wired and wireless connections to the same network, the wired is the 
default.
