How to set up PyAMF Django gateway so it uses AMF3 instead of the default AMF0?

From stackoverflow

• By default PyAMF supports both AMF0 (NetConnection remoting) and AMF3 (Flex messaging) of which RemoteObject is one flavour.

  The docs give a simple example of how to approach a PyAMF gateway with both.

  Also, you can set pyamf.DEFAULT_ENCODING = pyamf.AMF3 :-)
