I have to wonder if Roxio might know something we don't about Napster's application folder. It's not like Napster as a company ever really had a production facility, just a rather small application and some network and computers. Maybe Napster folks figured out something huge and Roxio wants to step in early.
Toast, Jam and Easy CD Creator are all great tools for making audio CDs, DVDs and backing up data. I imagine they might be offering some kind of online sharing facility to go with their other software. I'd say the hotline protocol is better than napster myself but who really knows what use they have for it ?
Maybe they plan on creating a commerical file sharing application or something along those lines.
