I will try to see if whirlycache meets our goals better (especially I want to look at the
way the diskStore behaves (I want to be able to limit the diskStore keys), and wether we can
access the eviction policy from within our classes, to be able to free some memory from cache
in a sensible way). I think those guidelines should be in the document I am planning (sry...still
in planning phase) to write on caching and best practices. Also the many store configurations,
in which errors are easily made should be (will be I hope) documented transparently. 

I am not sure if supporting many cache implementation is good practice. If there is a large
difference between the caches, where cache1 performs much better in memoryStore, and cache2
much better in diskStore, and cache3 is avergae in both, then I suppose supporting different
caches might be a good option (though, an easy lookup of which cache impl suits your app best
should be available. Then again, this documentation ofcourse is outdated after every cache
impl release)

I hope to see one cache being superior in every facet. That would make choices easiest.
