GNOME Do. The Google Instant of opening programs\files better than OSXSpotlight (do.davebsd.com)

The comparison to OSX's Spotlight isn't entirely fair - it's more akin to Google's QSB, Launchbar, or of course the venerable Quicksilver.

Is Gnome Do still alive? 0.8.3.1 was released in Dec 09 and I haven't seen any updates come across since then. I hope someone's still working on it. I love the project. (If I were less lazy and wanted to learn Mono, I'd take a stab at it.)

Edit: wrong release date

Besides Launchy, is there anything similar for Windows?
