The Ruby on Rails Rich Internet Application Software Development Kit by Adobe
Or RoRRIASDK, say that ten times fast!
The kit features six examples - and growing - of Flex/Fash with Ruby on Rails goodness including my Flash Remoting with Rails MP3 player tutorial. Big Ups to Mike Potter of Adobe for setting up the SDK and allowing me to contribute to it.
There’s also an Adobe PHP SDK if you’re so inclined.
