alot of the new ones have no real owners. unlike napster who stored hardware and software on their actual network and had the data(music in most cases) go over their networks. the new networks don't have servers set up for that. instead you download the software and the files are transfered directly. giving out the software isn't illegal at all. its how people use the software on these new networks that is illegal. you can't punish software developers because the software they are using is illegal. but you can punish networks such as napster that did all the work for them through their servers. i hope that is clear. if you really want to know about it more in depth there is a ton of info about it on the net.
