[Xastir] Maps won't cache

[Hal Mueller]

This smells to me (without looking at the code) like a tile cache size limit problem. I don't know what xastir used to decide how much map data to cache, but that's the setting I would hunt for. 

Another idea would be to generate data in advance. I just poked around in mailing list from late 2012 and saw some talk about using Mbtiles data with xastir. Mbtiles is a format for mass offline storage of raster tiles. It's supported by GDAL, and I think that means it works in xastir? You could use a program like Tilemill to generate full Mbtiles coverage for the areas you need. Side benefit (if it works): you can distribute the same Mbtiles file to all of your volunteers, minimizing training load. 

I'm also curious: does your event need all of xastir's power? Will you be messaging, gating, repeating? Or would a much simpler, dumber app, one that is "read only", do the job? I daydream every now and then about writing that one for Mac.
