Addon for warning about opened scroll gates out of Cyrodiil (for shard collectors)

[AlexFullmoon]

Well, see the title. To get those four elusive shards behind enemy Elder scrolls gates I have to monitor Cyrodiil map for changes whle I'm out questing or whatever. Is there a way to automatize this? Even better, something that will track key keeps status and inform you if gates are about to open.
