I am looking at content delivery using MPEG4.
This means VRML geometry maust be converted into BIFS (Binary).
Streaming Vizard plus sound and video in MPEG4 will involve middleware to integrate the streams and encode them
What issues does this raise for Vizard ?
:confused:

Are you trying to stream files or video of the rendered world? I don't believe either of the two has been tried before using Vizard, however I don't see any major issues in implementing them. Are you experiencing any specific problems?

MPEG4
MPEG 4 is a software layer on top of MPEG2. That is for "set top boxes, cell phones etc. It wraps together, using a common timebase, audio,video,graphics, 3D and scripting. BIFS is binary format VRML. The past limitations of VRML was that on load it would run till its end and could not pass controll to the user before then. MPEG4 allows user contol of all streams.

VIDEO
SO I need to stream BOTH prerecorded video and realtime 3D animation. Rendering of course of both are on the remote client machine. Video could be mapped as a movie texture withing the VRML or as a separate stream.

SCRIPTING
Can Vizard scripting be streamed as a separate component within MPEG?
Uh, If python is compiled locally, then no?
Both Java and JavaScript will be part of the MPEG4 streamcan be Demuxed and interpreted at the local client STB

SO,
No problems with Vizards standalone run just whatever may arise from the above
