It would be nice if MaemoMapper would have a DBUS interface so that external programs (like this one) can interact with it.
The mCacher could handle the cache and let MaemoMapper show, drive the user to the cache.
Ideally MaemoMapper could reply back, via DBUS again, the direction to follow (so that mCacher can show it as it does now).

This would be a pretty nice integration of these two cool application both related to GPS.
