If you're considering Collada, then I suggest also considering X3D (used to be
called VRML... remember that? :)
Advantages of X3D would be:
1. A ton of existing 3D content (converted from VRML97 or VRML1)
2. Open standard (ISO actually):
* stable spec
* no patent or copyright restrictions
* several implementation options, including GPL and LGPL
* not dominated or controlled by any one company, really
* relatively easy to join the Web3D Consortium and impact future
development of the format (Robotics Visualization Working Group anyone?)
3. Designed to be componentized and extended with new optional components
(called profiles)
