Getting the modules and making the tree is easy. Making the code work is hard. Yes, sometimes this will work... but if A passes an object from v1 into B and B passes that object into v1.1... that can blow up. If v1 and v1.1 both use any global resources, that can blow up. It doesn't sound like node addresses those problems at all, which are the only ones that are actually difficult.
