I was asked:

1. anybody out there want to write an X3D converter for this open-source codebase?
2. add it to the pile of candidate technologies that can be integrated into our forthcoming X3D Compressed Binary Encoding Call for Contributions
3. try to determine if any patents pertain.  am guessing not.

work in progress:
X3D Binary Compression Capabilities and Plans

all the best, Don
