Flash/Flex tools from Google

One thing that is worth bringing your attention to from IO is that the big G and Adobe have made public a set of libraries for ActionScript 3, i.e. Flash CS3 or Flex 3, called corelib.

The corelib project is an ActionScript 3 Library that contains a number of classes and utilities for working with ActionScript 3. These include classes for MD5 and SHA 1 hashing, Image encoders, and JSON serialization as well as general String, Number and Date APIs.

You can also see the docs online, and there are some examples on code.google too.
