Having re-read your original question, I see now that my answer
doesn't apply at all :P

To do this with appcfg.py download_data, I'd see what you can do with
the exporter class that you're defining for each model that you're
downloading.  You could add a timestamp field as I suggested, and
define a function in your exporter class that tests that this field
exists and/or is within a particular range.  From there, you could
either set a boolean value and use it to pare down your result set in
post-processing, or raise an exception.  You're probably not going to
avoid having to download every entity (without patching
download_data.py) as the functionality you're looking for doesn't
appear to exist.

Hope that's more helpful.
