My understanding is that this discussion is still related to what goes into
the proposed charter for the Layer 3 VPN working group. In this context
we don't have to solve the problem right now, we just need to decide
what goes into the charter. 

My personal view is that multi-AS one-provider is important enough that
it is worth mentioning in the charter. Multi-AS, multi-provider is probably
also something that we want to have as a possible option. Thus I think 
that we might as well mention these in the charter. 

I am not so sure about slowing down the base documents in order to 
get the multi-AS cases fully fleshed out. We have already slowed down 
the base documents to wait to finish the Framework and Requirements 
documents, and there is the possibility of slowing them down to wait 
for a security document. 

To me whether to insist on the inter-AS case being solved and fully
documented before progressing the solutions documents comes down
to three things: (i) How important are the multi-AS cases; and (ii) How
confident are we that if we postpone the multi-AS work, that we 
won't end up with a situation where we wish that we had changed the
base documents; and (iii) How long will it take to fully document the
inter-AS cases?

A question for Alex and Thomas Narten: Suppose hypothetically that
there is consensus to work on the inter-AS cases, and suppose that 
we don't want to slow down the base documents to wait for this to
complete. In this case, the L3 VPN working group might work on 
progressing existing documents (the long list from the proposed 
charter that Alex sent out) as a high priority item, and work on the
inter-AS cases as a lower priority. In this case, would we want to 
explicitly mention the Inter-AS cases in the charter?
