Do we think it is worthwhile to continue down the network/routing based
solutions? The lack of feedback on my draft suggests people aren't very
interested in working on this. If we want to do this at the routing
level, we have start exploring less obvious stuff. For instance, using
the flow label or diffserv code points to swim across the default zone
towards a network that knows more specific routing information.
In the long run that will be the only thing that scales - so that is
where we will need to find a "permanent(tm)" solution.
