given how many like their consuls 'pimped' with skins, there is a market for people handy with transfer making or an air brush to personally customise cases from the inside.
Love ir hate it, the iPhone always draws the eye, so this could be attractive as a business logo on company reps phones (even photo security passes), pic's of the family and so on.
imho a vast opportunity for those with the artistic skills, at little investment/overheads costs.
would this technique work on Ipad2's?
