keith, SIP may have been initially motivated by telephony style applications but it is a very general and extensible negotiation protocol - it was that aspect that grabbed my attention when I first heard about Schulzrinne's work on it several years ago. I think the point really is that SIP is extensible and may be a very reasonable platform on which to build a wide range of peer to peer and distributed application control. vint At 07:43 PM 8/20/2003 -0400, Keith Moore wrote: >Why in the world should IETF bias a conferencing solution toward the telephony >providers?
