Their website says a petabyte (1,024 terabytes) is being shared on the network and I believe it. On any given public hub, it’s not uncommon to find individuals sharing 250 gigs or more of data; usually feature films, console games, and software. That’s insane.
What makes it different from the countless other peer-to-peer apps out there? Instead of relying on a central server or networked nodes, DirectConnect looks more like IRC: public or private hubs of individuals, each acting as networked file servers. You can only search the files shared by people connected to your own hub, which means less files but increased security.
Plus, it’s easy to create a private hub for your company or a group of friends, undetectable to any unwanted guests (like the MPAA). You can password-protect your hub too, for the very paranoid.
One caveat: I’ve heard rumors that BayTSP, the anti-piracy firm that works for the SPA/RIAA/MPAA, is heavily monitoring DC for pirated material. Watch what you share.
