Thanks for your comments.

To move forward...

-Problem Sta= tement
Yunfei: are you planning to update draft-zhang-ppsp-problem-state= ment
before the upcoming IETF? Few weeks ago I posted some thoughts on t= he
problem statement.
   Yes,I'm happy to tell al= l of you guys that we have achieved substantial pplive support in PPSP.&nbs= p;I just visited pplive in shanghai.After discussing PPSP issue deeply with= James, I think we can shrinkle the scope of PPSP to a more practical&= nbsp;extent. 
    So I will update the proble= m statement draft before the upcoming IETF and I will consider carefully ab= out your vauluable comments on problem statement. I was a little busy at th= at time without replying your post in time.But I have thought over and disc= ussed your comments with otheres. I wil let all know the status of the= new draft.
-Solution Space
Song's co= mment: "Most current P2P streaming applications use
proprietary pro= tocols but they share the similar architecture(tracker
based and with CDN support). So want to develop standards based on
it.&q= uot;

How about documenting (I-D) this architecture? This draft could= serve
as a basis for our solution space.
 
Good suggestion. In fact, in the meeting with = pplive,we had decided to coauthor such kind of drafts.Welcome to join us. 
Thanks so much for your suggestion.Victor.
 
       &nbs= p;            &= nbsp;    Yunfei@Geneva<= /font>
Thanks indeed,
