Ah Ok. I'm glad that you're aware of this :). Your use case sounded very similar to the 2nd level cache use case and the reason explained earlier is why when using a standard 2nd level cache, caches need to be somehow clustered. Hey, once you've got the solution complete, why don't you write a wiki or blog explaining what you did? Other users might be interested in doing something similar without necessarily having to set up a cluster.
