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.
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.
