When I wrote "memory-based caching, a la membcached", I meant "memory- 
based _object_ caching, a la memcached".

When I wrote "the way forward", I meant that object-based caching is  
likely to buy us a lot more than file-based page caching will buy us  
over database-based page caching.

I certainly didn't meant to presuppose every site's situation and  
specifically said that this won't hold in all cases -- though, I'm  
convinced that it will hold in the majority of the cases.   Plus, I  
stressed that we'll want to do a rigourous analysis first so we have  
good understanding of the problem space.

Yes, see above. :)
