This was briefly mentioned in an article in the NY Times today.

It is a database of public-domain architectural designs
intended for use by disaster victims & people in impoverished countries.

The website's scheduled launch date is March 8th,
and it should be interesting to watch its development
as designs are contributed over the upcoming weeks.

I think it has the potential to become a powerful collaboration tool,
as well as a great new medium for distributing ideas about architecture
over the web.
