even a limited # of copies will still be expensive, but with the right sponsors backing it, it could be a possibility.. my opinion (from some experience at this) is that it would be cheaper to do a few songs from each artist than the complete show, granted you won't satisfy everyone to get their favorite tunes, but small steps lead to big ones.
Pre ordering would be an option as well with sponsors. Or perhaps limiting the # produced to actual tickets/GBs purchased for the show. It might be a pricey DVD, but I for one would say it's worth the bucks.
But one day as PP and Glenn keep gaining popularity and and a general feeling of "best event in USA", "best guy to work for/with", "best fans"... maybe some bands will start recording live or filming their own stuff for release.
How many of you would pass up the chance to pack the floor for ANY band that Glenn gets to perform if you knew they were going to record/film live??
It's very cool to be able to watcha DVD and see a show or song and know that you were there.
