Well I once heard from a rigger that you don't really need to stitch NURBS patches, as long as they maintain tangency. But he's some sort of rigging guru, so... (shrug).
I never stitch my models, just attach/detach and make sure they have tangency between them.
I have bound a couple of models so that I could pose them for portfolio pieces. The seam splits were not as bad as one would think, and probably with careful rigging you might be able to get away without stitching at all.
But then again, I am not a rigger, or an animator, so perhaps my opinion doesn't amount to a hill o' beans.
