Thanks for a neat hack. Here are some observations after playing around with it for half an hour.

- asui failed to start after installation. systemu was stopped fine, but asui was not started. Running "/etc/init.d/advanced-systemui stop" restarted systemui, and further "start" did just what it was supposed to do.
- Locking the device only locks the screen. Hardware qwerty-keyboard still works, power button still opens asui, long press of back button still closes active application.
- SSH widget doesn't recognise dropbear as SSH server.
- IMO locking the device through UI should hide asui.
