[Twisted-Python] Question on new code development

I am in the process of building an interactive game server and client with the client code written in Java and I have a couple of questions. I am hoping to be up and running with a prototype in the next month. My plans incluse the use of Twisted framework as I'm very comfortable in Python as well as Java. My first question is, should I be looking at the new Twisted 2.0 for development or stick with 1.3 and plan on upgrading to 2.0 later. Secondly, would using and/or building upon TwistedJava for the communications between the Java clients and my Twisted server code be a good direction to take?
