Re: [XCON] BFCP over UDP

[Tom Kristensen <2mkristensen at gmail.com>]

As a heads up, since personal draft announcements are not propagated
to working group mailing lists:

A new version of the draft associated with this thread was submitted a
couple of days ago.

-------------
A New Internet-Draft is available from the on-line Internet-Drafts directories.
       Title           : Revision of the Binary Floor Control Protocol
(BFCP) for use over an unreliable transport
       Author(s)       : M. Thompson, et al.
       Filename        : draft-sandbakken-xcon-bfcp-udp-01.txt
       Pages           : 14
       Date            : 2009-10-23
This memo extends the Binary Floor Control Protocol (BFCP) for use
over an unreliable transport.  It details a set of revisions to the
protocol definition document and the specification of BFCP streams in
the Session Description Protocol (SDP).

A URL for this Internet-Draft is:
http://www.ietf.org/internet-drafts/draft-sandbakken-xcon-bfcp-udp-01.txt
-------------

This submission aims at reviving the draft, to trigger further
discussion within XCON and to serve as a starting point for the work
on the outstanding issues. Refer to Section 4 of the draft for a
list/details of further work.

The draft is structured to ease merging into the upcoming bis-drafts
for RFC4582 and RFC4583 in a later stage.

Cheers,
-- Tom
