Is there a chance you can point us to a code snippet of said cache algorithm, or elaborate a bit? If it's simple and elegant in hindsight this insight might be interesting in other CS applications. Not cross sharing and reinventing wheels is a somewhat sad implication from the compartmentalization you mention.
