Sure, I'd be happy to see some contributions! Although I'd like to warn you, I wasn't able to get this to work; though I haven't really dug deep into this, so it may be possible.

I'd strongly suggest you to wait for the next release before contributing though. I'd like to fix some bugs first and do some code refactoring.
