You might be interested in this, Bofu2u put me on this yesterday:

Apparently someone Open Sourced a subscription with recurring billing platform which utilizes Stripe. Now if you understood what I said, Rails Boys might get a hard-on.
I don't know if dchuk's seen it, but its directly from the vault of Bofu.
This skips paypal and uses the latest Golden child Stripe, uses gay on fails, I mean ruby on rails, and is a recurring subscription platform to build off of.
Now imagine creating a service or business around setting up small to medium size businesses that need a solution that's more out of the box for recurring subscription, without gaypal, with your new skills?
Don't forget my 15%.
Good luck bro, I'm rooting for you.
