Use the iconize event. Unless I'm completely mistaken about OLPC (which 
doesn't do overlapping windows, right?) we're talking about users 
switching between apps which would best be represented by an iconize 
event. Also, depending on what you are planning to do in response I'd 
think that this maps more into "iconize actions" on other platforms.
