I think the main limiting factor for this is the scripting required to 
track all the files produced.  But I agree this is an approach we should 
aim for.

osmosis should scale linearly down to any time interval (within reason 
but 1 minute intervals is possible).  It can also combine multiple 
changesets into larger changesets if required.  Again, it's just a 
matter of tracking all the files.
