After reading the recent discussion of a "meta-microformat," I
decided to play around with the idea. I've probably gone through
9000 revisions, but I think I have a usable tool now, which I'm
calling "HTML Analytical Lexicon." What it does is parse natural
language queries and derive a semantic representation (internally
stored as RDF) using Princeton's WordNet:
http://wordnet.princeton.edu/
Then it searches an internal cache of microformatted HTML content
(converted via XSLTs to RDF) collected from around the web, assigned
meaning via XMDP if available, otherwise WordNet. It finally
translates the RDF result back into natural language results.
So far it seems to be working well. You can submit a query like
"Where is Tantek Çelik right now?" and it will find Tantek's vcard
info, match that against all the hcalendar data on the web, look for
a vevent matching the current time, pull out the location, and return
an answer like "Tantek is at home."
Because it uses WordNet to determine meaning of both content and
class names, it doesn't require formal definitions of microformats,
so it will work just as well for future microformats that haven't
been created yet or even unstructured formats individuals use in
their own markup.
I'm still making changes and testing so things may break, but if
you'd like to try it out, here are some example queries:

+now?
http://randomchaos.com/microformats/hal/?q=What+is+the+date+today?
http://randomchaos.com/microformats/hal/?q=Open+the+pod+bay+doors
Peace,
Scott
