Have you tried the distributed notification center??? It was designed to
allow applications notify each other in just such a case as this.
It would have to be done carefully:
- have to avoid an app posting a notif that triggers notifs from the other
apps
- need to make sure that the notif doesn't cause all the apps to pounce for
the same information.
