I would say yes. But I would also like to see some work done on

Both exists, and I worked with both problems. I don't think that they
are different enough from a technical perspective to make to cases.
However, from a implementation policy POV they are very different where
the second is the hard one.
The problem that need to be looked at is as well is if this create more
complexity than what you gain from implementing it. I think that the
VPN model given in the draft is a good model, but it is at the same
time way to simple, as I tried to show. Also, I think that starting
with a non MPLS network is easier, and would give hits at what needs to
be done for MPLS TE.
