Great idea! I would think an application, running on the monitored device, could read the profiles and logout the user if outside the usage time. Obviously the Koalasafe would need to allow access to the Koalasafe cloud, but this could be easily accomplished. Windows would be easier than iOS, but I would think even iOS devices could use the same method! Along with logout, a warning feature could be added to let the user know when their time is up.
