Dave Winer's xmlStorageSystem is a proposal to implement a hailstorm like cloud to store xml data. Bery interesting. I hope this gets broad support. Google has already some juicy stuff.

xns.org has been developing xns for several years and aims for the hailstorm space. it seems like every day brings a new initiative in the web services arena. note to self: i ought to write up a comparison of the various identity services that are being developed:

• hailstorm
• xmlstoragesystem
• xns

oh my!
