While the concept is pretty clear the development team is having some issue with resources ($$). You can read more about the concept first shown in the Android Dev Challenge at Androidandme.com. You can also show your support for the dev team by voting for them to help get some funding here.
I am pretty excited to see this project mature and release a workable version. In my opinion this would pretty much be cake for Android security which is already is ahead of the pack in this field.
