First Integrated Wireless Joypads?

Hi,

I have just finished integrating a Logitech G-RA4B wireless joypad receiver into my PS2, and it works great - all the benefits of wireless without the need to have wires and a receiver hanging out of the front of the PS2.

I have only installed one for joypad 1 at the moment, but fitting a second shouldn't be a problem, just need to buy another controller now I know it works.

Anyway, I was just wondering, has anyone else ever done this before? Or am I the first?
