Humanitarian Development and Design Conferences, Events, and Happenings

The two biggest humanitarian design events know of are (both are application/invite only for entrepreneurs–I assume they allow visitors to find out what its about, but I would ask the organizers on a case-by-case basis):

1) The Unreasonable Institute which is an entrepreneurship incubator-check out the great entrepreneurs, mentors, and Unreasonable Institute TV (hosted on Vimeo)
2) The International Development and Design Summit-check out all the great entrepreneurship and innovation projects from people around the world.

Upcoming & Honorable mention:

So Cap 2010 (October 4, 5, and 6–Social Capital Markets Conference hosted in San Fransisco I believe)
Tech 4 Africa-African Tech Conference (August 12th and 13th in South Africa)
