Oh my gosh... help! I surrender! :)

What I intended to say was: a lot of analysis on streamability has
gone into this subset of XPath. It's worth looking at, and the mailing
list archives are worth looking at because there was a lot of
discussion on axes, predicates, one-lookahead for text node children
(which enables a few types of predicates to be evaluated), and other
issues that anybody who attempts this will run up against. The
discussion included a number of people from this list, including
Michael Kay.

Then people could read up on it, rather than post messages like "I
heard through the grapevine that predicates generally don't work with
streaming". Then again, I suppose, it's fun to do analysis from
scratch. Ah well, whatever it is, it'll be good to see streaming
processors!

I think you would find that the STX contributors would make very
reluctant dictators indeed... :)
