I checked it out on SuperNova. It was too goddamn confusing (I have a limited attention span and no cliffnotes were provided) so I moved on. But I read about it in Maximum PC. Basically, it is P2P but with less bandwith absorbency because it allows files to be downloaded in pieces from others who are downloading at the same time. It's still P2P and still illegal in most cases (because of the files being shared).

But fuck it; you want it? D/L it!
