I think this is happening because Xastir has to download the necessary tiles.  Has anyone come up with a way to download all the maps you'll need for your area and keep them local so if you are in an area without Internet access your maps will continue to operate?

Okay, that makes sense.

Another piece of the puzzle would be the possibility of downloading map data *before* going on a trip so you can have the maps cached.  I guess I can just surf around on the map but that takes a lot of time where a script would likely do better.  If no one is working on this I can try to figure out how to make this work and provide some code around making it happen (likely a script).
