Hi Grendel, I think it should be possible to cook up a script that would export a separate STL file for every object, I'll see what I can do.

There isn't really any proper way to store multiple parts within one single STL file itself, the STL format was mainly intended to store just one solid in the file, it just has a big heap of separate triangles in it with no connection information. If parts don't touch it might be possible for a receiving application to sort things out but if they touch it's pretty difficult to figure out which triangles were supposed to go with which particular part.
