RE: [XCON] Control Values and the Data Model

["Brian Rosen" <br at brianrosen.net>]

I don't think we really need to change permissions during a conference, but
I don't think it's very difficult to allow it.  I think that you need a
permission system to be able to define who gets to view and/or change what.

I think, for example, in most systems, you can get a roster, but you won't
be able to see the details of all the streams each participant is sending or
getting from the mixer.

I do think that some controls will be available only to participants in a
role.  The example you are using (mute) is not a good one, because the user
needs to control his own mute, and moderated conferences need the ability
for the moderator to control it.  I can even imagine defining a floor, where
getting the floor changes the state of the mutes automatically.

Yes the control (to mute outoging stream of all the participants) is
given only to moderator role. If I understand correctly the basis for
classification for roles is the privileges each role is assigned. So for
a basic audio template an moderator (or any other role name which we
want to use) would have the privilge to mute the audio streams of all
the participants. Anyways we have to define in the templates what roles
are being specified for this conference and what controls are available
in each role. Are you suggesting that the privilges (or permissions)
assigned to each role would change during the course of the conference ?
