User A GETs a resource and edits it. User B GETs a resource and edits
it. User A PUTs the modified resource back. User B PUTs her version of
the modified resource back, unaware of A's edits. A's edits are lost
without anyone noticing. What I want to happen is B to get a 409
"Conflict" or some such.

There are no replication requirement in this project.
