I could easilly see this overlapping with the dawning age of cybernetics, imagine a computer you just think to intereact with.
With the right tweaking these nanotube structures might even be able to serve as a sort of scafforld to help repair damaged nervos tissue, like retnas, cortex, possibly even spinal injuries. Or how about combining it with that snake reserch to make a 'new' sensing organ.
I'll be happy with just a second set of arms though.
