Hi there, I've done a lot of work with importing .dae files in papervision, so that is not a problem - here's a virual DVD shop I created: [login to view URL] (Click the TV logo in the top left) which imports a DAE, and populates it with dynamically created DVD cases.
So I pretty much have the basic code for this ready and waiting to go..
Interface-wise, I can make it very easy for new models to be added, without the need to edit the actionscript.
