If you'e talking about purchasing music via iTunes yes you can do that. But for the non-copyright mp3/4's being shared, yes Limewire is a tool to use to share with others. Depending upon your OS platform, for mac OSX: As soon as an mp3 had dwnlded, it will be copied into the iTunes own library. Once you connect your iPod, iTunes will copy your iTunes song list across to the iPod. I'm not sure about the present version of Windows Limewire, but I think this process will be happening very shortly (I read some time ago that this was being introduced) if it isn't already existent. But the process of copying from iTunes to iPod (I should imagine) will most likely be equivalent. There's plenty of people very happily using the LW-iTunes-iPod combination!
