James, You have it right about the proper solution path.. I think we have a Redis one in there now too that might be interesting (not in 1.3.0 perhaps but..).
We offered a simple out of the box one early and to ensure the interfaces are right. Since then the community has popped up some real/stronger implementations like you're mentioning.
