“We could then venture to produce a mixdown that would be ready for fans at the end of the show.” 

This technology has been around for a few years...glad to hear they are considering this. Probably the best way to build out the fan base. Give a friend one of these who has never heard them, and they give one to their friends, and so on and so on.......I do that now with the archive stuff, but a Sam produced CD would be so much better!!
