Of course the MPR selection must still be "large enough" to be RFC sufficient. 
I discussed the idea with Thomas Clausen in Vienna and he said he doesn't see 
a reason why it should not be RFC compatible.

My idea was just to have to "dump" nodes that give the "master" olsr to 
communicate over interfaces not connected to his own machine. Maybe just a 
tunnel protocoll or something like this.

The idea was developed in some chats in Vienna (okay, "developed" is a little 
bit much). I did not thought much about the physical structure of 
Freifunk/Funkfeuer before...
