I'm not sure about the development state of Jyhton, but like others have already said, using the JVM opens up an enormous box of Java platform goodies. With Jython you can build your web app front-end with Django and your backend business logic with Java, Scala or something else. It also gives you the ability to create worker thread etc.
As of last week, Jython 2.5.2 was released, which is with some benchmarks is a 20% performance boost. I'm told that as of Pycon this past weekend, Jython 2.6 has been officially started, which will bring Jython closer to what you currently get with CPython 2.6 (library wise, etc). I can't speak for the project, but my guess is that it'll be sometime next year before that gets to an alpha state.

This is a great online book about using Jython: http://www.jython.org/jythonbook/en/1.0
