I'm a little confused about why this is targeted specifically to mobile. I've been looking for a back-end only CMS for years now. Originally, I didn't mind just having my front-end share a database with my CMS, but it would be even better if it used a RESTful API like you've got here.

Maybe I'm missing something? The closest thing I've found to what I'm looking for is: http://www.pureedit.com/ and storageroomapp.com seems very similar (although much better) judging by the Introduction Video.
