so do I :)

the dtml only iterates over some objects.  each object has a method
which checks the authenticated user and serves up content
accordingly.  in the test case the user is served the default view of
the object, so there's not really all that much logic going on.
perhaps this is why non concurrent, cached requests showed only a
1.3% speed improvement over uncached requests.  anyone?

I already read this in the online help, but for some reason my brain
only chose to understand it just now ;)

hmm, just had a quick 20 minute poke around, and I get the gist, but
I'd be happier if some obi-wan could guide me with the api docs
promised in the fishtank proposal
