Java EE Application-scoped variables in a clustered environment (Websphere)?

Is there any easy way in a Java EE application (running on Websphere) to share an object in an application-wide scope across the entire cluster? Something maybe similar to Servlet Context parameters, but that is shared across the cluster.

For example, in a cluster of servers "A" and "B", if a value is set on server A (key=value), that value should immediately (or nearly so) be available to requests on server B.

(Note: Would like to avoid distributed caching solutions if possible. This really isn't a caching scenario as the objects being stored are fairly dynamic)

I'm watching this to see if any simple solutions appear, but I don't know of any myself. Last time I asked something like this, the answer was to use a distributed object store.

Our substitute was manual notification over HTTP to a configured list of URLs, one for each Web Container's direct server:port combination. (That is, bypassing any fronting proxy/web server/plugin.)
