I just published a new version of SabreAMF, and it includes support for the flex2 messaging system. This means you can now use flex2 remoting with great ease.
It also includes a callback server class, which is now recommended for use with flex2. This class handles the standard AMF3 stuff like CommandMessages and translates Exceptions into ErrorMessages.
You can download it here. You can find an example on how to use the CallbackServer class here. An article on how to use this will follow shortly.
