The Laszlo Platform, which is kinda like Macromedia Flex, was just released as open source (under the Common Public License).
I'd looked at Laszlo Platform a while back, and it was pretty cool, offering dashboard-like stuff, sorta like Macromedia Central meets Sherlock meets Konfabulator. Kinda cool for dynamically generated flash content and widgets.
Open Source announcement here, and thoughts from the company's CTO here.
It's kind of like Flex, but without coughing up $12K per CPU on the server. Might come in handy for a Pachy 2.5 (or 3.0) authoring interface...
Thanks to Matt Raible for the link.
