I have seen discussions on this before...basically setting up a couple of stands in the section, then broadcasting the signal over a wireless access point. Seemed to be a nice way to handle taping, in that patchers and tapers can be anywhere in the place and get the signal. At the time, I remember thinking that besides the technical issues, which there are some, that something like this would really freak out some of the artists.
The ABB for example have said that the reason they allowed taping in the first place was the copies were good memories of the show, but not as good as their commercial releases. As technology caught up to them, they realized that AUD tapes were getting better and better. After much consideration, they agreed to continue to allow taping openly, partly because of their fanbase expectation, and partly to help curb bootleg sales, but they did not want electronic transfer of files. The stated reason was that they felt that something like that opened them up to the possibility of bootleggers getting a copy of the show and reselling it. Whereas with personal interaction, rather than mass distribution, there would be less chance. While I don't necessarily buy this argument, I can see where they are coming from.
Point being though, if these wireless networks ever got going, I think that may push bands that are just cautious or paranoid, to reconsider things. Because of the perception of the more technology, the better the output theory.
Besides, I would not be interested, cause I dont want to haul all of that crap around...I have enough crap
