Two conflicting things:

- To bind high level objects, node copying is probably not a good idea.

- Node copying is necessary to avoid some direct in->out paths.

It's probably harder to avoid node copying then to simply support some
kind of "virtual binding" operation.  I.e.

		<virtual> r9 = p_delay_update(r8, si->r2);
		so->r10 = p_copy(r9);

in any case, removing the copy-node part seems possible and gives a
clearer view.
