  Nice diagram! I wish the Hibernate doco had some diagrams like =
that....

  What I mean by "transactional access" is we would have to be able to =
read a value out of the cache, check its timestamp, and then put a new =
value in the cache as an atomic operation. Currently we do this by =
synchronizing on the strategy object. That approach won't work for a =
distributed cache. I detailed an approach that would work (a remote =
LockServer) in a previous email. If you read that carefully you will see =
exactly how isolation would be broken without it.
