EHCache and JCS POC - Auxiliary cache question.

[Buddy Guy]

I am doing a POC with EHCache and JCS, starting with JCS. I am having difficulty limiting the size of an auxiliary JCS cache using a RemoteCacheFactory. I believe I can do this with an IndexedDiskCacheFactory by setting the MaxKeySize attribute, but this isn't available for a RemoteCacheFactory cache. Does anyone know how to do this? Other than Apache's documentation, there isn't much available on JCS, and even less on auxiliary caches and how to use remote.cache.ccf properly. Any information or links to helpful documentation is appreciated.
