Idiot proof Bitcoin SCI for digital downloads?

[Lethn]

So I've had a look around and so far I've seen some solid ( if confusing ) SCI scripts for Bitcoin that seem to work great for selling real products but I haven't seen any so far that offer options for digital downloads. Is there an open source script like bit evolution where I can directly take payments without needing any third party to do it for me and charge a fee? In case you were wondering I was thinking of something like Direct2Drive or GoG.com where you get an email and login page that gives you download links to what you want after you pay.

For those curious I've signed up with bitpay and plan to use their PhP script alongside a script I paid for called Digivendor Pro ( Really awesome by the way ) I was wondering if there was an open source version out there but oh well at least Bitpay won't rob me in fees like paypal seem to want to.
