That would seem extremely useful.  I was thinking about notifications as well, and my first thought was just to notify on every recovery (if you've selected RECOVERED).  That way you would know if a single host kept doing a down/up/down/up/down/up type of thing.

This would work alright in my environment since hosts that go into error for any length of time tend not to fix themselves anyways. :)
