I’m happy to confirm recent stable Linux kernel IPv6 subtrees cache problem is 
fixed. No need to do something special here, just give in some ip -6 route add 
default from PREFIX [ via ADDRESS ] [ dev STRING ] commands.
Sure we need to have a distribution mechanism having all routers know some form 
of (source_prefix, exit_link) mapping. If we take the limitation to support 
only default routes, a simple border router discovery and recursive FIB lookup 
will do. Select the route to the border router, or, on the border router, use 
the right exit link.
@Fred: I suggest you add my BRDP proposal in your list of efforts. No code yet. 
It is the blueprint for MultiSmartGateway for v6 in olrsd2, to replace 
SmartGateway tunnels which are used in current olsrd.org code.
