         No, the point is that there are lots of ways around the ECMP
problem, as is evident from the fact that most vendors do ECMP
differently from everyone else.  What seems clear to me is that
through the use of a PID in the PWE header we can clearly
identify what is in the packet regardless of these mechanisms.
