It seems to me that an RDBMS could "absorb" the cache functionality if it became much more "object aware" and more easily distributable.

there are many people who 1) have serious scalability problems with their database, and 2) could cheaply use a distributed cache on a bunch of cheap, ethernet-networked machines and solve their problems.

I know.
