<br>
I did some private (hobby) studies regarding multiuser mode and rather complex
scenes (combining content from different authors) and would like to ask, if you
could second my experiences,<br>
<br>
or if somebody disagrees (the whole project is documented at <a
href="http://simulrr.wordpress.com).">http://simulrr.wordpress.com).</a><br>
<br>
See below<br>
<br>
I am aware of Network Sensor and DIS, is there something else in the standard,
that can be used for multiuser mode (besides SAI/EAI)?<br>
<br>
Thanks in advance<br>
