Lastly, it would still be cool to be able to get a diff of a database from
X date that could be used to sync changes to remote offline databases.
That would mean if you have a 5GB database, a 2GB USB drive, and 1GB in
changes since X date, you could still send the sync on the USB drive.

Yes, something like a patch file or the binary archives that some version-control systems
support.

This would be useful in several different scenarios. Essentially it allows asynchronous replication
via other communications media — you could replicate via email or Dropbox, in addition to
a portable drive.

This seems like a better idea than copying CouchDB database files around. That file format
isn’t especially well-defined, and might change between versions, and there are replication-compatible
databases like TouchDB that use entirely different file formats.
