I suppose the answer to that is "it depends".  If I am doing a lot of
mapping I'd likely update daily.  Otherwise every few days is fine too.   I
suppose there's no harm in auto-generating it every night though.

I'll have to look into the size of the diffs.  Ultimately my goal was to
consume as little server resources as possible.  I figured there was no
sense in downloading the whole area every day when relatively little
changes.
