After playing with it for couple minutes, they have some interesting features set up for BitInstant Beta.

New Features
ACH (linking bank account) [Not working yet]
Debit Card Purchase [Not working yet]
"Instant Debit Transfer" (less than 24 hr ACH) [Not working yet]


Something "Interesting"
While signing up, it appears like they may be pulling credit history info (unconfirmed, don't panic!). I say this because they asked questions like:

1) Which of the following street addresses have you lived at before?
2) Do know any of the following individuals? (family member listed)
3) Have you ever had any of these telephone numbers before?

And so on, more to come...
