ok, so if you see my other post I'm clearly missing something.
I don't dispute that we might need some new features, but I don't see
that what you have said is an answer to Nevin's question. For me
you've answered a different question.
Whether Seaside's REST support is stateless or minimal or not does
not prevent the current API from doing bookmarking. It sounds like
you have a different goal?
