Would it be a workable option to have fully referenced diff files, next 
to the current sparse format?

Would there be a lot of overhead in generation and/or filesize?

With the current interest in hourly/minutely updated maps, this seems to 
me to be an interesting option for people that don't or can't load the 
whole planet.
