Hi, folks
	We have submitted a document, named as “A SIP-based P2PSIP Client Protocol”, to explain our viewpoints on P2PSIP Client and P2PSIP Client Protocol.
	Currently it is available at http://www.ietf.org/internet-drafts/draft-li-p2psip-client-protocol-00.txt
	Based on the discussions on this list, it seems that the main difference on P2PSIP Client Protocol is around whether the Client Protocol should be SIP-based. In our points of view, we think it should base on SIP not only for the compatibility with existing SIP devices but also the simplicity, flexibility of SIP. Besides, the term "SIP-based" does not exclude other protocols for some particular service. Currently, SIP is extended to exchange service-related information between clients and peers for service discovery and service location (this function need the cooperation of peer protocol), other protocols can be utilized to access the services.
	The details of our design are explained in the draft. 
	
	Comments are welcomed.

Sincerely yours,

Yao Wang
