we've talked about version numbers in regard to making syncing more

suggestion of examining the last-modified date in combination with the
etag is a more interoperable way of doing the same thing, though. yea,
time is fuzzy, but for the use we're talking about, etag+last-modified
would be sufficient almost every time, i'd think.
If the last-modified values we're comparing are all issued by the same server
then it should work as well as a version number. It's comparing client time
vs server time that is flaky.
Err, and only as long as the server's clock is not reset back in time.
