I am afraid I share some of the concerns expressed by Avshalom.

The reason for including the basic Floor Control Protocol as a part of XCON
is to be able to use it as the tool for building various applications when
"lecture with questions/answers" and "voting" being some of them.

Therefore I suggest including the motivation as a part of the Charter:

"The basic Floor Control Protocol will provide the tools for building
conferencing applications such as lecture with questions/answers and voting.
Standardization of the Floor Control applications is out of scope of XCON"

and removing the stand-alone "out-of-scope Voting" statement because it is
one of the many examples only.

Orit.

Subject: [XCON] Floor Control: Its usage.
Message-ID: <A3851AA1B761E944912B20D1E95A7EFE08B49D@radvpost.RADVISION.com>

I admit that the Floor Control piece is less intuitive to me that the other
XCON components. I don't know whether I am alone, but I think it can be
helpful to show the usage cases of the protocol in the Floor Control drafts.

In draft-koskelainen-xcon-floor-control-req-00 I suggest expanding the
introduction section (or introducing a new "high level requirements"
section) by showing more floor control applications (i.e. conference
modes/types) that are going to be the customers of the Floor Control
Protocol.

In draft-wu-sipping-floor-control-04.txt I suggest showing what it takes to
implement a simplest audio conference with lecture mode and
questions/answers using the primitives defined in the draft. (Of course,
more examples are welcome.)

Thanks,
Orit.
