I think the copy culture aspect and it not being available online makes it better. If you are online, you can listen now, and for the offline crowd you can always get it on conferences or try to snatch a copy (PoW :) ). Maybe you could try some dropboxes or local "seeders" on select conferences and such. How do you actually produce the copies? I suppose you run multiple decks at normal speed?
I now have a duplicator that can do 2 copies of a 40m tape in 6 minutes. It's slightly less quality than real time copies but cassettes have a upper limit anyway. And I still enjoy listening to them so I wouldn't say they are bad sounding. It saves so much time.
