Console Peripherals on PCs

I’m getting a XBox 360 Elite for Christmas so was doing some digging around in regards to the extra stuff and the costs of games etc and I was wondering about peripherals…

Does anyone know if the peripherals for the 360 can be used on computers? I ask this because I know the controllers can be used if the USB receiver is bought first and installed, but was wondering about the Wireless Headset? Also, the LIVE Camera, can that be used? I know that you can use the PS2’s EyeToy Camera as a webcam with unofficial drivers from the Internet, and people had already interfaced their Wii remotes with their computers.

Was wondering if anyone else are doing, or have done, bridging of other wired/wireless peripherals that were meant for consoles, to their computers.
