Thanks Jonah and Michael, I'll give the utility a tryout!

My problem with seperating parts is the polys don't line up at export time - reworking the topology in the poly editor is hella painful especially for curved surfaces.

That's why I'm hoping that MOI will keep track of the polys generated by the mesher and can assign them based on the surface being meshed...

PS - I see the MergeOBJ and SeperateOBJ links lead to the same SeperateOBJ download, is that correct?
