It would be nice if this plugin could provide a custom URL field for enterprises that have GitHub deployed locally. Possibly even allow for multiple to allow for both the Public GitHub as well as a private GitHub. The API should be identical between both public and private. Organizations that deploy a local GitHub need this for data and intellectual privacy and protection. But that doesn't mean everything they do is only in the private GitHub instance. Also allowing for both Public and Private GItHub would allow organizations who also contribute to Open Source via GitHub.com to be able to track both sides.
