I guess you expect me to disagree :-): We consider the major 
contribution of the PS to bring densely together all the different key 
aspects of the problem space. This is indeed not a trivial collection 
and cannot be "easy reading".

The problem we had with all the other drafts was a very partial focus 
that missed major parts of the problems - leading to confusion and also 
to the diverse positions arising at the previous BoF (remember the wise 
words of Rajeev).

So our argument would be: if you carefully read the PS, the "real" 
problems of multicast + mobility will be very clear. Details on specific 
tasks can then be easily derived by just doing transfers.

I promised to work on this - however, I would put higher priority on the 
BCP-type solution for PMIPv6, so I beg some patience.

We had a volunteer just two mails ago.

Yes, I guess so.
