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.

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.
