If there were only 2 choices (as your question sort of implies), I'm
pretty sure the developers would have done it that way.

Since xastir supports so many different maps (formats, projections,
yada yada yada), each one gets handled on the fly.

Now, some sort of "no monkeying required" format might be nice, along
with some tools to re-format (pre-render?) your favorite maps...
