Sigh... with special thanks to Robert S. who pointed out to me in a
offlist note that I completely, totally, and embarassingly forgot about
that wonderful little thing known as the If-Modified-Since header, I
gotta say that I'm feeling wonderfully silly at the moment. I'll blame
it on an acute lack of sleep brought on by the arrival of Snell Kid #3.
... in any case, just pretend that I was talking about the
If-Modified-Since header all along and go from there.

add a "Last-Retrieved" http header to the GET request. The server

RFC3229 w/ feed [1] has the same concept, using ETags instead of dates.
This is not really invention ;-) and I already proposed using it for
syncing.
