Hi Jens, A useful discussion of music and digital technology is found in Chapter 2 (Music: Intellectual Property's Canary in the Digital Coal Mine) of the citation noted below. This book most assuredly does not use ANT, but it still offers a solid analysis. National Research Council (2000), The Digital Dilemma: Intellectual Property in the Information Age, Washington DC: National Academy Press. Please write me off-line about your work as I have done some work on file sharing that may be relevant. Cheers, david neice ~~~~~~~~~~~~~~ David C.
