For those who expressed interest in the pre-dispatcher code I’ve been experimenting with, there is now an updated dispatcher.rb available for download.
This one appears to be much more robust in the method used to track down the “built-in dispatcher” and load that code first. If it can’t find the built-in one, it’ll fail silently so that your Rails application can work even if the pre-dispatcher doesn’t.

Thanks to Hans Fugal for testing the original dispatcher.rb code.
