I know several "clubs" and/or internet discussion groups that have made member contributed tapes to share among the groups. The Cyberpluckers autoharp list is one and the contributions on their tapes are fantastic. The tapes have been distributed at cost to the members that want them until they run out. In effect it is an extended song circle. The contributions on these tapes were limited to Public Domain items, or the performers original works. This did constrain what was included.I was wondering how these types of projects would fit into what you are describing above. They are more like home movies than anything else. There has been a vigorous discussion in the past on the Cyberpluckers with some very strong opinions on the copyright/intellectual property side being given, and vice-versa.
