Word is that Yahoo is poised to announce that they've reached an agreement to acquire Konfabulator, and will confirm the deal on Monday. If you're not familiar with Konfabulator, it's the original version of Apple's Dashboard; a Javascript runtime environment that lets anyone create standalone mini-applications (aka "Widgets"). Unlike Apple's Widgets, it's also cross-platform, and Yahoo has said they plan to extend the program's current Mac and Windows versions to Linux, and possibly to handheld platforms as well. Yahoo plans to offer Konfabulator for free, which may not be a welcome announcement to anyone who recently paid $19.99 for it, but should guarantee wider distribution for the program. Konfabulator creator Arlo Rose will apparently stay on, as Yahoo's Director of Widget Technology.

Update: The deal is official, and there's good news for paying customers. Anyone who has paid for Konfabulator 2.0 is eligibile for a full refund. Not too shabby.
