The use of downloaded Google Maps tiles is interesting; I wonder how long until someone writes a map viewer for PalmOS which uses these, effectively cutting into the market share of programs like Tube (which have limited coverage, and often annoying qualities such as being unable to scroll between map tiles; a pain when you're looking for somewhere just off the map, or in the intersection between two tiles). Then again, Google may be able and/or obliged to use the DMCA against any software which attempts to use its map tiles in this fashion (though I am not a lawyer).
