I am not sure this is the right pair of settings. First of all, the discussion in Minneapolis was of the opinion that there could be a number of algorithms. I am not sure whether these are configurable using CPCP, but first come first served is only one of the automatic ones. It is even conceivable that one of the actions of the moderator is to regulate the order in the queue (or "set" as we discussed in Minneapolis).

Secondly, I have assumed that for floor control, there will always be a moderator, and therefore there will always be moderator control, it is just a matter of whether the floor can be automatically be granted elsewhere in the absence of a moderator instruction when the floor becomes vacant.

Not sure automatic timeouts are useful in a conference. This to me would be moderator action. If people want it, then it must be settable to infinity.

Additionally I would add:

- Assignment / removal / replacement of the moderator to the floor
- Is it possible to have more than one floor in a conference, e.g. in relation to multiple media streams. The moderator for message chat may be different from the moderator controlling the audio-visual, but they could well be in the same conference.
