What's the consensus on db caching?

It would seem like that road is the lowest-common-denominator -  
perhaps the only way to performance-enhance for restrictive shared  
hosting envirs.

There are several levels to start with - caching whole pages, a la  
movable type - but dealing with frequent cache invalidation (who said  
this was the most difficult problem in computer science?). Lower level  
caching - of the post object, comment objects, etc - should be worth  
it too. It might not enable any old shared host to survive a full- 
scale digg+slashdot attack, but might let one hold up a smaller rush  
of traffic.

Is db caching worth it? Is there any demand for it? Does it exist  
already, in some ready form?
