I think, sugar should take care of this if an activity do not want the suspend feature. When the suspend locking activity has been finished and there is no other activity that is locking the suspend "/etc/ohm/inhibit-suspend" could be removed.
Maybe an activity could attache a line in /home/olpc/.inhibit-suspend with it's activity name. When the activity is done, this line will be removed from itself or sugar. If there is no line left in this file sugar could remove /etc/ohm/inhibit-suspend.

Classes and activities could use the same file as mentioned above?
