For those not following the AT topic that might still be interested:

It is still a work in progress but at least you can see that progress is being made (I know that in Nxt land progress is generally measured in days rather than weeks or months).

We have already come up with some interesting ideas beyond the two current use cases such as a "Term Deposit" AT that would earn you NXT by leasing your forging power for x blocks then return the initial balance + forging interest to you and I think James will probably blow everyone's mind with some of his ideas.

The more I look at the flexibility of the Nxt design the more I think it really is the "next" thing. I just hope that TF can be proven to have no attack vector (beyond a 90% stake ownership one).
