I've been playing around with a way to control an Android device that is hooked up to a projector which will make it great for showing off apps in meetings. The setup I'm using consists of a Galaxy Nexus runninng a TUIO client, a Kinect, projector and a MHL adapter. With an AOSP build of Android the TUIO client app can be signed with the system keys to allow TUIO events across all of Android and not just limited to the TUIO client app.
