I have to agree with W. James Au - this is pretty big. Possibly gamechanging.

If you look at that and think to yourself "um, that sucks, why would I care?" -- it's not for you. It's for the people who think MMOs, virtual worlds, and hell, even home computers are the realm of the terminally dorky - but have consoles.
Again - this has the potential to be *really*, *really* big.
(Especially once someone hacks it to be R-rated...)
