So Overclockers.co.uk have come up with a Wireless SATA connection using the 2.4GHz spectrum
It's mega expensive and only works at SATA 2 speeds, but the idea is brilliant in my opinion.

Makes it even easier to hide the main storage.
Imagine when Mobo manufacturers build these into their Mobo's and supply the adapter for the HDD.
