Well, I think it's fair to insist that the underlying filesystem
efficiently handle as many files-per-directory as you find in actual
AFS filespace (that is, if you have 10,000 files in /afs/foo/bar/,
it's fair to insist that the underlying filesystem cope with a
10,000-file directory).

But if you're using the FS as a block-storage mechanism, then yes,
what the namei server does is the right solution.  Most web browser
caches (Safari, Mozilla) work this way too.
