RAM caching is useful for "subtemplates."  I am not convinced that we
should think of "resource level" caching (AHCM or Andy's "bake-to-disk
on the fly" solution) in the same framework as the tools like RCM, which
are much better suited for caching intermediate results, but don't scale
well for entire pages.
