If you want to do your presentations in Emacs, consider eslide: <a href="http://github.com/jrockway/eslide" rel="nofollow">http://github.com/jrockway/eslide</a><p>It is like takahashi.xul, but everything is contained in Emacs. That means your syntax-highlighted code-blocks look the same on your slides as in Emacs :)
