Running CherryPy on Android:

Combining the two to run a CherryPy app on Android, which allow you to take a snapshot remotely by visiting http://x.x.x.x:8080 from a browser in the same LAN segment.

It needs to acquire at least a dim wakelock, otherwise it won't work after android goes to sleep.  Have to kill the app to release the wakelock though.
