Having read some posts here and tried to use Limewire for FTP downloads, I must say that I prefer by far the Audiogalaxy service. Too bad it is limited only to sharing music files, but it surpasses Limewire and Mactella by far. I suppose eventually some will start "Napsterizing" the files and make the MS Office installer "MS Office v.X Retail.dmg" into something like "MS.Office v.X Retail.dmg.mp3" so it can be traded on AudioGalaxy

You can find an unsupported helper application X to access the Audiogalaxy servers, for Mac OS, at Bigger Planet - Sputnix.
