I'm wondering if EDD can point to a file hosted at Assembla, the site which allows private Git and SVN projects for free, on contrary to GitHub which charges for private projects.
I've read you've been working on a Dropbox addon. It is very nice. In addition to it, it would be also really nice to have an addon for Assembla integration so that we don't have to upload files to the server hosting the WordPress site but simply commit the files to the repository.
The problem is that a file url hosted on Assembla is variadic and changes with the revision number like,
rev=e380f951926deae4e07363380cbd2e09 changes after each commit.
