With NUTSS the destination is (probably) seen in routing from the
start, but signaling is required to set up a desirable path.  Here the
problem is that neither source nor destination is globally routed.

I'm concerned about scaling.  That's a lot of dynamic state in the
core routers, precisely where we don't want it.  He's probably better
off source-routing.  See NIMROD
<http://ana-3.lcs.mit.edu/~jnc/nimrod/docs.html> and remember what it
stands for! :-)

He should also see the proposals in the Routing Research Group
