we currently use the collada loader to load models, but they don't have
any advanced requirements, yet. For one project we used .3ds models and
a 3DS max plugin to export some material information (some state
settings, textures and shaders; shaders were written outside of the DCC
tool though).

We'll probably need some more features in the collada loader, but some
stuff might end up in separate files again, depending on how application
specific it is.

that is an interesting question, but I don't really have a good answer.
Collada at least has stuff in there that can transport this type of
information, but I have not looked too closely what available exporters
write - the loader currently does not handle shaders.

hm, I have had a preliminary version of the code, but if memory serves I
never got the final code - perhaps I misremember this though.

it can load geometry and to some extent the profile_common materials
(although I'm always very uncertain about what the "right" mapping from
collada to OpenGL is), and since yesterday or so it also loads the light
sources from the file.
It can not handle profile_CG or profile_GLSL stuff at this point (do the
exporters write this properly?).

I don't know the answers to this, sorry.

hm, hard to say. I'll be working on adding some more features to the
collada loader, but that will primarily be driven by requirements from
the projects here. Animation is something we will need,
bump/displacement mapping is much lower on the list though.

no, not really ;(
