I've noticed some native caching is coming for Couch 1.1.0 [http://www.apacheserver.net/memrioa-management-at1047105.htm 
], but know no details.

Yes, in many cases "expiration" based caching makes sense.  
"Validation" based caching would be really handy, though. But maybe as  
non-trivial as cache invalidation of view results, fulltext queries,  
etc based on changes of individual docs...
