Interesting! Does it also work on non-rooted Android devices?

No it unfortunately does not. You require root to remount the read-only system partition, to insert the kernel modules, and to turn SELinux off. We used a "userdebug" build to get root, but I imagine most of this could also be done with a phone rooted through other means (I haven't tried it, however).
