Just wanted to reference a post I made today about the infrastructure that I've recently setup to make our Drupal "stack" into a scalable e-learning architecture that supports self-site / course creation as well as pervasive user accounts and centralized user management (I can't think of any other buzz words at the moment :) ).
https://elearning.psu.edu/projects/node/131 -- infrastructure / multi-site stuff
https://elearning.psu.edu/projects/node/129 -- screencast / course manager module
https://elearning.psu.edu/projects/node/130 -- outline designer
Anyway, here's the repostings about the topic but I was more so wondering if anyone else is doing anything similar so that we could combine efforts. I see a lot of talk about "here's how to setup drupal to do xyz, Views is a must..." or "look at this cool new feature" but very little discussion of infrastructure developed to deploy / manage large scale drupal implementations via multi-site for organizations / networks / universities so I'm putting out this probe to see if anyone else has given it any thought.
