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. :)
