I'm sure in theory someone could mass produce the relevant component in the DX that gives wireless functionality. In other electronic devices (Sony Playstation, Xbox, NDS etc) people have figured out ways of altering the hardware to bypass regional and technical restrictions.

As a first step, someone needs to open up a US DX and a DXi side-by-side and identify the relevant component.

Next, you would need to see if by swapping the components around, wireless functionality can be attained. If this were to work, maybe at this stage users could offer to swap hardware components. I know for instance there are US users who are unhappy with their DXi and 'global' users unhappy with their DXi.

Just a thought ...
