oh and we are not using Verse for anything either, just mentioned that 
it is not similar (as it was discussed recently for other reasons).

sure, but earlier i did not think that Collada would have other 
benefits, than the format and the existing tools that support. it. being 
able to add stuff to the files doesn't help, if your tools wouldn't 
understand it. and for a tool, like opensim, that does not support it 
yet, it wouldn't be different for using an own custom format.

but indeed the idea of somehow adding the SL specific things in Collada 
files may be interesting if there are some other parts of the spec that 
are compatible to start with (dunno how the creator etc. things are 
there, for one, and other metadata for example). and of course for 
systems that support meshes too, like Rex.

i'm not exactly sure yet how the technical details will go, but 
certainly it does not hurt to see how things are there (and why not e.g. 
x3d too..)
