I didn't realize a collada exporter was so important. If so.. I have a *very* *tested* and *very* *small* collada importer in my middleware stuff (~3k lines of C++ code). It supports pretty much everything (models, skeletons, materials, cameras, lights, morphs, any-axis orientation, animations with matrices or curves, etc).
Given it's very small size and non-dependency on OC, it's very easy to understand and *very easy to mantain*. It pretty much just ignores conformance of input files and just attempts to grab wathever data it needs so *compatibility is extremely high*. It's not a standalone library, but it's separated enough that *if someone knowledgable of blender internals *wants to give a try to adapting it to blender (of course with me 100% available for answering questions with this), i think in a matter of a few hours we can solve the Blender problem of collada import support. However as I said in previous mails, I really lack the time to get familiar with Blender internals and do this myself.
