The key of course it how you define state equality. In my view state equality means that if you were to serialize the objects to byte streams, which neutrally represented the entirety of the state, equivilant objects would have identical serializations.

But you need to decide what you mean by the object's "state" before you can decide how to serialize it. So appealing to serialization doesn't help here at all.
