BroadQ’s QCast Tuner for the Playstation 2 is a $49.95 disc of PS2 software that’s run on a networked PS2 with a broadband adapter. The package also contains a piece of PC software which lets the PS2 browse and stream the contents of the PC via the PS2 connected television.
That means you can stream music, video (including DivX) and even MPEG2 stuff from DVDs. It’s as cool as this ArsTechnica review suggests.
