Introducing Braintree.js

I have built quite a few rails apps using TR. The braintree ruby gem makes the whole process very easy. I would hesitate in using this because you still end up explaining a lot to during PCI compliance. IIRC during the PCI compliance my customers had to do a whole lot of work even when we were using TR. Splitting your process into multiple steps and doing validation using JS is much much easier IMHO.

If anyone is using this, I'd love to hear about their experience. We default to recommending Stripe to our customers, but will probably need to offer Braintree support in the future as well (in case they already have a Braintree account and want to use that instead of creating a new Stripe account).

Seems to use a different approach to Stripe, using encryption rather than API hooks/callbacks.
