Completely lock the device
I'd like the ability to prevent someone using a device for a period. This could be combination of a device lock, along with a passcode change, or some "auto" way to push a device into single app mode with the SimpleMDM app as the only one, with a basic "device is locked until xx" message.
This is just a situation where you want to prevent device use until you re-allow it or a way to stop the device being used for anything until a certain time.
If you could do this as a feature, this would be huge with the parent mdm crowd too.

Nick... Putting the device into Lost Mode should cover that need. As long as it is supervised.
