I will do a detailed review a bit later, but I think we need to mark the 
IPv6 encapsulation as undecided, and I think that we need to have a 
serious discussion in the WG about the proposal to perform an 
intermediate triage of duplicate packets. Doing the triage at S-PEs adds 
a lot of complexity and posiibly a lot of silicon expense whereas a 
simpler approach that would be to do standard 1+1 or even 1+n and 
de-duplicate at the edge of the network. So I think we need to donsider 
that as undecided at this stage.

I am not sure what the scaling constraints that are proposed are, but 
S-PE can have huge numbers of PWs flowing through them.
