hi Kevin -- I think you missed my point. I accept NXT's limitations. What I'm saying is, we *can* do the sorts of things I outline, with the platform as given, if we get enough developers interested in contributing. I was going to post this anyway, (...)

good analysis. Also keep in mind that Lego sells primarily through retail resellers, so their take is considerably less than the SRP.
