I keep hearing references on the nonprophets about the existence of a near-complete repository of all the episodes from the beginning. Some time back Russel mentioned on the show that he had all these sitting on his hard drive for posterity, and more recently Matt mentioned that the new ACA library would have a computer with all the shows stored.
I understand the older shows can't be made available online for bandwidth reasons, but how about burning all the mp3's on data DVDs and selling them on the products page, similar to how the older AETV DVDs are sold? I'd love to hear some of the old stuff. :)
