Even if it had to be via Ajax or something.<br>

DIS and XMPP are examples of application protocols that the network
sensor was designed to support at a portable node level - i.e. without
requiring a proprietary java or C implementation. Perhaps there are
alternative ways to do this in portable X3D code, I don't know.<br>

Anyway, I agree with your summary statement.<br>

am thinking that people who are interested in graphics and those that
are interested in MU networking are different folks. Here we have a
bunch of graphics weenies who have essentially bought into the DOM, and
forgot about GLX/XGL or whatever the networked OpenGL was (perhaps it
was too slow or not scalable?). Now WebGL is taking over the role of
GLX/XGL, and the DOM folks are trying desperately to layer on top of
it. Hence X3DOM. Perhaps when people think about browsers, they think
in terms of a person accessing a server, and they don't see peer to
peer interaction. They also think about how slow it is to go through a
server. Guess what? Google is already doing multiuser stuff from the
web with XMPP (google wave). And guess what else? NetBeans can
provide for simultaneous editing of X3D with XMPP (X3D Edit). If you
want a MU protocol, why not or why not choose DIS, Open-DIS or DIS-XML
(encoded with EXI)? Note that I have not programmed to XMPP or DIS. I
have tried to create unsuccessfully, an X3D scene to add arcs and nodes
to an X3D scene (yes, I've done it with JOGL). Perhaps more effort
needs to be put into an easy to use, standard dynamic scenegraph that
is implemented across all browsers, and the question about MU protocols
will go away. Yes, I realize this dynamism is verboten, but it's why
people program in WebGL, JOGL, OpenGL instead of X3D or VRML--It looks
like X3DOM will provide a way to add and delete nodes in HTML5. Is
there appreciable impact on performance by making a dynamic scene?
What about IE?<br>
<br>
In summary, get a standard dynamic scenegraph working the same in all
browsers, and your MU problems will go away.<br>

<br>
For beginners DOM = retained/structured mode<br>
WebGL = immediate mode<br>
Two styles of programming graphics.<br>
