The GigaOm blog has a writeup of Redmond startup Twango (not to be confused with Seattle's Dwango Wireless, which changed its name to Dijji last year and is now out of business).

Twango builds on a digital-locker concept and adds social sharing capabilities. Its free service offers unlimited storage and 250 MB per month of uploads.

The company was founded in 2004 by five former Microsoft employees.
