Heyo I'm a big fan of Besieged but I seem to miss out on it a lot. I've been thinking it would be really cool if there could be some sort of iOS/Android app that lets you choose your FFXI play server, and alerts you when an enemy group is done training and is on its way to Al Zahbi.
In addition to this, maybe the app could be configured to tell you when campaign is about to begin in [S] regions that you specify.
I got this idea from a Square-Enix licensed iPad game called Wizardlings. When my mp is completely full and I'm not playing the game, it'll chime telling me that it's ready to go, and it has been really handy.
