Actually I'm integrating it into app_meetme, since it's the application we're
using as a basis for Confiance (http://confiance.sf.net), a prototype
implementation of the IETF XCON framework
(http://www.ietf.org/html.charters/xcon-charter.html), which is the
conference control protocols Sergio is talking about. The integration with
Sergio's mixer also includes the mapping of floor control with video source
enabling: which means basically that video can be moderated by means of a
dedicated protocol (BFCP) standardized in XCON instead of using DTMF.
However, I'm sure integrating it into app_conference would not take much
efforts, and I'll be glad to be of help if needed.
I've been talking yesterday also with Ramtin about jis work on the subject.
It seems that our current developements are very "synergistic", and both of
three have a very similar idea of what needs to be done.

From a general architecture point of view, the system will be split in three
main functionall blocks: a signaling server, a conference unit, and a media
procesing server. Each one of us is focussing it's work in one of the areas, so
i think it will be great to collaborate an integrate our projects together.
(I will also invite anyone to join, expecially Francesco, who has made an
excellent work in the h324m project).
The signalling server will deal with the sip negotiation, and it would need
to be integrated with the conference unit. This could be integrated in asterisk
or be in a separate server (Ramtin work).
The conferenc control is what Lorenzo is currently doing, a central unit that
will handle resource reservation, floor control, and probably web interface for
admin and things like that. Currently his work is been implemented integrated
with app_conference.
And the video mixer (my part) will only deal with rtp streams, performing
encoding/decoding process and media mixing. It will be controlled by the
conferenc unit via an http/xml protocol. The current api is this:

Sounds promising! Sure I can try to convince my boss and other companies
or friends to help with the bounty. I've been looking for this feature
for a long time, even if it's a CPU eating thing. I thought it was
almost impossible to convince anyone to do that work in Asterisk...
until now!
Good luck,
François.
