@Matt, I guess I didn't really answer anything - sorry. :) I haven't tried cloning meshes after they've been added to a containing mesh - or I did when I was working this code out and I've since forgotten. It may be that the Mesh is attempting to merge the added mesh into its own geometry as a sub-geometry, which is why you aren't able to access it in a manner similar to how you added it.
Glad I was able to help. Yeah, my own solution is very far from ideal - I wrote it in "get it done" mode.
