I just sit down and uploaded the material used for my recent presentation at the JRSL 2009.
The source code for the demos is in this zipped file, with the exception of the full django project I ran on top of Jython which was taken verbatim from the Jython Book.
You can take a look at the slides below (via slideshare) or download the slides as a PDF document here.
Finally, if anyone from the audience is reading this post and is also going to attend to the Encuentro Linux in two weeks, I want to tell you that I don't plan to repeat this presentation verbatim, but to do a much more demo-focused presentation. I'd like to hear suggestions on what area you would like to see more comprehensive demos.
