Tony,

Fair enough. The definition of map-encap has been expanding to a
rather liberal scope recently. Perhaps we should seek a stricter
definition.

Though I wonder if there's a reason why we shouldn't strive to make
our map-encap system as expansively capable in the inter-domain scope
as MPLS is in the intra-domain scope.
