This and the mass pay option in Paypal is what keeping us from migrating. I was/am? still working on a better fraud model for Paypal that could easily be swapped out for Stripe given the similarities between the payment provider responses.

Not that I'm promoting Paypal's fraud controls in any way. They're terrible as well.

The way I see it now, Stripe made it easy. If they could lock down the secure aspect they'll run away with the game. Integrating with something like maxmind might be a good direction for them to look.

Edit: Just noticed the Stripe Apps functionality. It might suffice for an alternative to the mass pay functionality that Paypal provides. This just got a little more interesting.
