Anybody familiar with this, and/or know how one would use this?

I'm guessing you'd plug the PC Card into a laptop PC, but would there be some sort of PS2 emulator from Sony you'd use with it? And, assumedly, you'd need a proper driver for the card, also from Sony. I doubt support for the card is included within linux kernels, OSX, or Windows.

Anybody actually KNOW about this, as opposed to my idle speculation?
