We need to be able to specify host/port combos, file names, output directories, etc.

Allow specification of just x/y (zoom is specifiable already), and skip intelligently instead of just looking for a matching tile.

Only one thread gets a tile to download first, then the rest wait indefinitely for a tile to show up.

Abstract tile downloading by forcing the user to provide a 'TileSource' class that encapsulates the tile download itself.
This would aid in testing by allowing the creation of arbitrary tile sources, so they can (for example) simulate error conditions.

This would require calculating, or at least estimating, the number of tiles that will be downloaded.

It would be nice to see (for reference) an overlay of the tile coordinates at the (for example) lower right of each tile in the map. It should include the latitude/longitude, x/y, and zoom for every tile. The overlay should be toggle-able.

Change the current download() implementation to use the 'logging' module instead of print statements.
Also change the command line options to support selecting particular log levels (default to something sane, like 'error').

While downloading, keep track of downloaded tiles by writing to a special 'continue' file.
Allow the user to specify one of these files so we can pick up the download where it left off.
