The linux-zigbee scheme will handle the case of multiple border
routers better since it has more memory for running the border
software.  For the Contiki stack to handle that it would have to be
aware of how the non-802.15.4 network routes.

For example, say you have three wifi/802.15.4 routers on three
different stories. It is better to get an Internet originated packet
to the wifi/802.15.4 router that is on the same floor. That will
minimize the mesh hops.  In a large commercial building  this will
make a big difference.

This is part of the RPL spec, but I don't think anyone has implemented
it on any system yet.
