I have discussed the requirements for the cache from
the CMP's perspective (PersistenceManager) with Jeremy
twice (and we'll meet this Monday again). I think we
came up with a workable solution, the first cache
iteration was unusable (hashmap based). The new
tree-structured cache should suit your requirements
much better.

For stuff like "delete all order items form customer
with id=34425", we need some custom functionality,
agreed. But I think I have a solution for this, and
Jeremy and I will discuss it Monday.

Other than that, I *hope* that the current API more or
less satisfies your requirements.

Maybe, but I do hope the cache can be used by both.

Why not ? If the cache satisfies both requirements I
don't see why we could not proceed in parallel.
