Linux (and most likely windows) wont like this.

Olsrd creates generic ip routes, so the kernel would be unable to determine 
the outgoing interface for packets.

Just define one subnet for each channel. This way you don't need any kind 
of "location dependent" information.

channel c:
  10.c.0.0/16

So you can just think about your net 10.0.0.0/8 splitted into 255 "channel" 
subnets.
