monitoring an amount of use of the of the at least one device;
determining at a plurality of times that the monitored amount of use is greater than the maximum allowed use;
modifying a value based at least on an aggregating of the determining at the plurality of times that the monitored amount of use is greater than the maximum allowed use;
determining when the value crosses a particular threshold; and
disabling at least one of a particular application or a particular functional component of the at least one device responsive to the value crossing the particular threshold.
