Hi Morgwen!
Yeah man, FastTrack (Morpheus, Kazza, Grokster) is fast and modern. When you follow new discussions on the_GDF, everyone is suddenly crazy about superpeer, swarming, file hashs, parallel downloads, automatic researches and metadata... I'm really really looking forward when all this is added to Gnutella!! Hehe, funny when I think back a few month, when really nobody liked this ideas or rumours about how bad Morpheus (or Xolox) allegedly is. Do you remember?
