Testing unknown apps with appium / open source project open to participate

Hi everyone, I would like to notify you about the open-source project “app-check” (more info at www.app-check.org). We are developing an interesting appium-based approach to automating a completely unknown android-app.
The use case here is to test apps from the play-store for privacy-issues. But the test-automation approach might be interesting for other scenarios as well.
First draft is out here: git.app-check.org but there is still plenty to do, anyone interested is welcome to participate.
