Another potential solution (requires a bit of invention) would be to
add a "Last-Retrieved" http header to the GET request. The server

GET /collection-uri HTTP/1.1

Last-Retrieved: Sun, 6 Nov 2005 12:00:00 GMT
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
