<div>Hi Sven-Erik</div>
<div> </div>
<div>Let me do some additional remarks regarding your statement "<span style="font-size: 11.0pt;font-family: Calibri , sans-serif;color: rgb(31,73,125);">Ejabbed are originally based on LM Ericsson system for phone switchboards and are fast to setup connections and transmit packages."</span></div>
<div> </div>
<div>I do not like to argue about which protocol is better suitable for session setup/teardown, either "Session Initiation Protocol (SIP)" or "Extensible Messaging and Presence Protocol" (XMPP), that's up to the future and I do not like to influence that.</div>
<div> </div>
<div>However, I think regarding the media plane, we have at least two different topics:</div>
<div> </div>
<div>First we have scene state that is transmitted rather seldom and must be transported reliably (e.g. "door open", "door closed"), so I guess "XMPP over TCP" would fit the requirements.</div>
<div> </div>
<div>On the other hand we have (quasi-)continuous state, e.g. avatar positions, positions of cars, and so on. In this case, we have a (quasi)-continuous stream of events, where it does not matter, if a few events are lost. I'm not sure, whether this wouldn't fit better to some protocol like RTP over UDP. (I know, RTP does not completely fit to needs of 3D scenes, because RTP relies on a continuous clock with equidistant time intervals, where 3D scenes do not have constant frame rates).</div>
<div> </div>
<div>Not to forget voice chat.</div>
<div> </div>
<div>I guess, there is a lot of know how about such issues in the community of multiuser server developers. Thus I am not sure, if it is the best approach to invent the wheel another time. Could be an argument to have a "truly and completely open solution" (open protocol (IETF), open interface (X3D network sensor)).</div>
<div> </div>
<div>All the best</div>
<div>Christoph</div>

<br/>
The XMPP Extensions Editor has received a proposal for a new XEP.<br/>
<br/>
Title: Sensor Networks - Control<br/>
<br/>
Abstract: This specification describes how to control devices or actuators in an XMPP-based sensor network.<br/>
<br/>
URL: <a href="http://xmpp.org/extensions/inbox/sensor-network-control.html" target="_blank"> http://xmpp.org/extensions/inbox/sensor-network-control.html</a><br/>
<br/>
The XMPP Council will decide in the next two weeks whether to accept this proposal as an official XEP.</span><br/>
