Very interesting - I'll take a closer look.

Q. what about the .x3z scene zipping
www.cloudvr.net
which is like googleEarth .kmz - a doc.x3d in the root of a .zip file, and /images subfolder - or other docx style resource bundling - does that fit with the manifest and chunking methods you use, or does your method replace/obsolete these bundling methods?
