Handover of detected location to plugins
Offer a Broadcast to plug-ins that hands over the location which locale detected (even if it is not a set location in locale). This way 3rd party apps can process it and give back a condition that fires a setting.
This has significant security implications, as Android apps must normally request permission to get your location. Users are notified of this permission at install time. If Locale were to start handing location over to all plug-ins, then this security feature would be circumvented.
I think the solution taken by the Locale SMS position Plug-in is best, where the plug-in will determine location coordinates for itself when it is fired.
