I like that you used Stripe for finish weekend itself... we just leveraged Stripe in our project for a finish-weekend-esk hackathon in Boston: http://www.vampirehackathon.com

We created http://hipay.me - a simple credit card invoicing system which lets you use your stripe token to collect payment from others, without being a developer. We are a finalist - awaiting word on the winner! http://vampirehackathon.com/escapes/27?page=finalists

Best of luck with Finish Weekend!
