I wonder if you think about (things like) Hazelcast?

It is JVM based "shared cache" so can be used to transparently share results of expensive queries - but also to share sessions. It mostly just works but the free version have some issues when one upgrade data models.

I know half the people here probably loathe JVM but once one is aware of one implementation I guess it should be possible to find similar things for .Net and maybe also go and Python.
