It would be awesome to have DoneDone-support. After a lot of research this turned out to be my favorite issuetracker/todo-app and its a big part of my workflow, right beside Beanstalk.

Hey Guys -
We've got a pretty solid API and set of webhooks, and a couple of different flavors of wrappers (python, C#, php). What more could you want? Let me know and we can help roll it up.
BTW, some documentation: http://getdonedone.com/api
