Microsoft wins patent to exploit network potential of skin

Mmy first reaction was rather along the lines quoted here:
"Some civil liberties groups have expressed concern over Microsoft's move. 'Body parts, in this case skin, should not be in any way patentable,' said Jim Thomas of the ETC group, which monitors developments in technology. "There are big questions here about whether individuals will be able to refuse this technology if it is used in, for example, tracking devices."

Am I being paranoid, or is there something unpleasant/creepy about having our bodies patented 'over our heads'? Or have I misunderstood what's been done here?

On a slightly different tack, the last five paras or so are intriguing, especailly the stuff about a rubber hand that was incorporated into test volunteers' sensoria ...
