While we're at it, why don't we just call it "Super iTunes?"
Napster's new "SuperPeer" technology is neither super, nor peer-to-peer. It's a proxy cache.
What's worse, it's a proxy cache that requires a boatload of IBM hardware (I assume customers like Penn State are paying for the tin).
A real P2P solution would have delivered all of the benefits of a big, dumb cache behind the firewall, but would have used mostly spare cycels, bytes, and bandwidth that already existed. Pity.
