Using the zoneinfo database seems to be the only way to avoid this sort of problem — clearly, the developer can't update the plugin every time the law changes somewhere! There seem to be a number of ways to hook into the database, so maybe pblair will take that on one of these days!

It would be great if I could map my Adium status messages to appropriate Skype ones. (That is, my "I'm out" Adium status is best represented by "Away," but my "On the phone" Aduim status would be better represented by "Not Available."

Hard to work out the best method for that, I imagine! (Maybe a drop-down in the "Edit" dialogue for statuses in the Status prefs?) But it would be much appreciated.

That would be fantastic and, speaking personally, it would meet my needs quite well. I have more than one contact that use no IM service but Skype.
