Wow, this is great. Thanks for the link. I hope to take Selfstudyclassics a little farther than this one goes over time, but this would be a great place for anyone to start.

The other resource you might be interested in is Minimus, designed to introduce Primary school children to Latin, and to allow non-Latin speaking teachers to lead a course. None of the interactive elements you offer, though there are CDs :) http://www.minimus.com/
