Nate,
I tried to respond during the site outage, but obviously wasn't able to. Sorry for the delay.
I guess the issue is that I almost never use pivot tables as a front end. I always create a report that draws from them, which leads to a very different set of needs and resolves what you are talking about in different ways (Lookup tables etc.) In my positions, I've been expected to analyze the data myself and provide an 'answer', rather than providing my audience with the ability to manipulate the data.
That's really of no use whatsoever to you. Mostly it is my way of saying 'I have no idea'. :)
