yes, the collada loader was only written for 2.0.

I'm not aware of one, but perhaps someone has one :)

IMHO the trickiest part about collada is to get the instantiation of the
various objects right. This is especially hard if you try not to deep
copy everything and also because in Collada nodes can be instantiated
(giving a node effectively multiple parents) which does not map very
well to OpenSG.
collada-dom (sourceforge.net/projects/collada-dom), the dom library the
2.0 loader is built on, seemed to be dormant for a while, but recently
had a new release (not tried it yet). There is also openCollada
(opencollada.org), which seems a bit more active, but has a different
API, so using that would result in a completely different loader ;)
Cheers,
Carsten
