After a while, you now have the post commit web hooks with Indefero. The hooks are modelled on the Google web hooks.
Basically, you register an URL in your project management area and after each commit an authenticated POST request is issued against the URL. The payload is a json fragment with information about the commit.
It is already available in the hosted forges. If you are hosting your own instance of Indefero, you need to pull the latest changes from the master branch to get them.
