Sounds reasonable.

The ideal formula would probably not depend on the actual earth surface 
covered but on the actual amount of OSM data. As long as entire 
contintents contain less data than Central London, let people download 
entire contintents ;-)

But that would require a special index to be kept which would slow down 
inserts - and the whole idea was to make the system faster not slower.
