I agree with Don, I think OpenACS (Open Architecture Community System) is the best way to go. People already know the name and why confuse anyone.. also might help pick up from people who were using aD ACS and want to continue in the same vein.
I picked up a copy of the aD Uni courses and I will be putting it online at http://projects.kinetx.com sometime in the near future (we have a 780KB/sec piece of a T1). Anyone have any suggestions on Linux streaming software so people? Also we are looking at buring individual course on DVD's (about 2 per course) and distributing them at a reasonable cost (cover the cost and a fee to support ADuni efforts).
