Sorry, I'm making a different point.  In Mark's proposal, there are multiple
parallel transport connections, each of which could in turn benefit from
ECMP.  The point is that within the domain and outside of the domain, his
approach can make use of ALL of the available parallel paths.  That's not
possible for any single transport connection.
