WPMU as OCW Platform

We’ve been using WPMU to power our OCW project in the David O. McKay School of Education for a year now. It’s been extremely straightforward and simple to run – every course has its own blog on the WPMU instance. Tons of plugins, drop dead simple migration… I love it.

However, as we ramp up to include more participants this year I’ve started wondering about the URL structure of having multiple departments participate. What I would love to do is still assign one blog per course, but be able to organize these under “subdirectories” as follows:

http://open.byu.edu/ipt/692/
http://open.byu.edu/comd/411/
http://open.byu.edu/eime/515/

&c. You get the idea. I haven’t been able to spend a ton of brain power on it, but I can’t figure out how to get the /ipt/ or the /comd/ in the middle there. Any thoughts?

Also, I’m wondering what to do URL-wise about courses like IPT 692. This is an Advanced Issues seminar and is taught multiple times each year by different faculty. Multiple times each semester, in many cases. How should I proceed? /ipt/692/wiley/? And how should I archive these? /ipt/692/wiley/2009/fall/?
