To solve this problem at the BBC in the guts of iPlayer, we used memcache. We *didn't* bother updating the cache if the DB contents changed though, as we didn't mind the user's view being a few minutes out of date. I've spent quite a bit of time thinking about how to solve this in the general case, and not come up with anything that works yet - not even anything that works in theory and goes arse-over-tit in practice.
