Sounds like he want to pick DaT's brain.
That's more or less what he said: that he wants public review of the ideas planned for Nxt. As seems sensible.
If he had a solid solution he would be releasing without the fanfare. Just my opinion.
He says he's concerned about clones. Also, some of this stuff depends on a robust ecosystem, which isn't in place yet, but hopefully will grow over the next few months.
(I'm not saying I agree with this approach, but I can see the sense of it, and there's no doubt the Nxt developers have delivered in other areas.)
