] Until last week, it appeared that Apple Computer Inc.'s ] iTunes Music Store had solved the problem of how to sell ] music over the Internet with just enough digital security ] to satisfy nervous record labels but not so much as to ] deter consumers from using it. ] ] ] But a few enterprising Mac hackers figured out how to get ] more mileage from one of the built-in features of iTunes ] 4, streaming music between Macs on a local network (such ] as a home network). ] ] ] Within a week of iTunes 4's introduction, Web sites such ] as ShareiTunes.com and Spymac were offering lists of song ] collections that could be streamed from the hard drives ] of dozens of online Mac users who made their collections ] available. ] ] ] Streaming, it should be noted, is distinct from ] downloading. When you stream a file, it's like listening ] to the radio; no file is transferred to your hard drive. ] Many Mac users doing this believed that since they were ] just listening and not downloading, the activity was ] legal. ] ] ] Before anyone could start debating the legality of ] streaming, however, other clever hackers devised a way to ] use the sharing function to download songs from one ] another's drives.
