In short, vDC copies object trees with shared nodes correctly. If one
instance in the tree point is pointed to by two others in the tree, in the
copy this instance (ie. a copy of it) will be shared as well.

vDC is the way to go for potentially very large structures/general uses
(such as the ability to duplicate any morph), whereas it is probably
overkill for well defined and/or small copying purposes.
