We must take care with terms here.... I believe both Torbjørn and 
Torbjörn would be interested in a regime where registering "torbjørn.se" 
would not be allowed if "torbjörn.se" was already registered by someone 
else. But that's bundling, not mapping. And the "default member" of the 
bundle (the one that actually goes into the zonefile) would be different in 
Norway and Sweden.

(btw, .no doesn't support bundling at this time. I don't believe .se does 
either.)
