UPDATE: I was wrong about who was behind the project. I made some assumptions. You know what happens when you do that... It's a collaboratiive effort, started (apparently) by Charlie Lowe (et al).
Boris and Will have been busy... They're working on a distribution of Drupal that is tweaked for use in education: DrupalED.
I'm not sure how much of this distro is just pre-selecting modules, and how much is hacking on the core, but it's cool nonetheless. It's still pretty young, but it would be trivial to switch weblogs.ucalgary.ca to a different distro of Drupal.
At first glance, it looks like a pretty much stock Drupal distro, with FOAF and buddies thrown in...
