Microsoft's new search - Built on open-source • The Register

By all accounts, Powerset will drive Microsoft's latest, ill-fated attempt to unseat the Google search monopoly. In March, a Tweet from Powerset co-founder Barney Pell set the blogopshere a-burbling about the impending relaunch of Microsoft Live Search, and days later, screenshots of an internal beta - dubbed Kumo - rose to the surface of the web.

When Kumo launches, in early June, it will be the first "shipping" Microsoft product backed by open source code. That's the word from Robert Duffner, a senior director in Microsoft's platform strategy group.
