this book seems to give good insight for my doubts. Since i had many dinner discussions with all kind of "sound artist, new media artist, also net artist", often a common solution is blurred for integrating their practice to art space, or exhibiting space, the situation alike, if any art piece is out of the general capability of white cube, the coordinator and curator would not pay appreciation to the movement of immaterial labor, of course, it is also for artist to rethink the approach of interface design in physical world.. its good to forget about the form of "screen" sometimes...this book has a "very" interesting collective aspects ;')
