New subtitle sources

So i’m using Infuse for the new Apple TV, iPhone and iPad for a while now and I love it!
The feature to find subtitles for tv shows and movies is one of the greatest features for me.
Although it’s a great feature, only subtitles from opensubitles.org are available.
From my experience the English subtitles are almost always available, but for my language (dutch) this site isn’t always sufficient enough (subtitles are sometimes uploaded late or not at all).
Is there maybe any chance to add new subtitle sources like subscene.com?

Subscene has toyed with the idea of creating an API that apps like Infuse could access, but unfortunately it has not yet come to pass.
