I don't think that they will ever be able to produce a machine that can see you in all your naked glory by looking through your clothes, how would the machine be able to produce the skin texture and tones etc from an xray for example ??.
I think that is just a fantasy that has been dreamed up from various films in the past and has been ceased upon by the press.
Now a machine similar to the one in Total Recall (where Arnie runs through and you just see his skeleton running with the gun) will become a reality as they show up just what is needed and nothing more and if it did become a reality, it would really speed up the security process for everyone.
