In the mean time, you can follow along in the git repository. Including the drama where 10 minutes before presentation time I merged in changes from my cohort that deleted 90% of the files, and then I blindly pushed those up to the public master.
You can look directly at the Vroom slides from http://github.com/spazm/config/blob/master/slides/slides.vroom . I'll render those to html and push them somewhere for viewing.
Omnicompletion actually worked during my talk/demo. I think that's the first time I've ever actually had it work. Totally exciting. While preparing the slides and doing I found that I was missing a configuration option in my vimrc, so my ftplugin/perl directory was getting skipped.
