P2P VoIP using SIP and Open Standards

Every operator/portal/service provider/mso [Yahoo,AOL,Gizmo,Comcast, Verizon,EarthLink,etc.] out there are rushing to create, or recreate, an IM VoIP soft client that has all the appeal of Skype with open standard compatibility. Since the most predominant and most promising VoIP protocol out their is SIP [Session Initiation Protocol] we are seeing a migration away from proprietary protocols towards SIP. The next significant phase in the growth of IP communications will include open standards P2P VoIP. David Bryan and Cullen Jennings, along with a boatload of very smart industry leaders in the IETF, are working on new extensions to the existing SIP protocol. It's called P2P SIP. After looking at the draft I would say it has a ways to go yet but I can see where this technology could become very useful to all VoIP operators like Free World Dialup operated by Jeff Pulver. & his new CTO Henry Sinnreich. Apparently they think so too considering they are looking for a response to their RFI which includes an earlier component of P2P SIP called Chord. Even operators like Vonage or device manufacturers like PhoneGnome and Linksys PAP2 could make use of P2P SIP. Everyone is looking for a new solution for P2P VoIP, I think P2P SIP is the answer, do you? Read the latest P2P SIP draft and tell me what you think.
