Ubiquity

I don't think this one's been forwarded to the list yet. It's a lot more
"now" than the Aurora concept, and it clearly needs embedded metadata:

Of course, they mention "Microformats" in passing, but this is a lot
like SearchMonkey in your browser: you really need to be able to add
your own fields and trigger actions based on the data.

Very cool prototype,
