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.
