I'm a big fan of the visitor pattern for writing network clients and servers. You basically add an accept method to your message classes. When the IoHandler gets a messageReceived message, you can use a visitor to handle it depending on the exact message type.
You can use the visitor pattern in a bunch of other places as well, such as in your encoder to write more specialized encoders for each message type.
