You might want to consider collaborating on building out Pagure[0], which is a git forge that enables decentralized development.
Pagure supports submitting pull requests with Git repos on any server (regardless of whether it's running Pagure or not) with its remote pull requests feature. Issues, docs, and pull request metadata are all stored as git repos using JSON files as data, making it easy and portable to other Pagure instances and easy to convert for any other system. This makes it an excellent base for building decentralized development workflows with the oft-expected Git forge interface model. Since all the stuff is in Git repos, they could all be backed by dgit, for example. :)
