Telepathy?

Could we ever arrive at a point when we can simply read off each other's minds, as sci-fi speculation in the manga series Ghost in the Shell suggests? It's very hard, I believe, if not impossible, to decipher inner thoughts. One way to do it, some say, would be through speech prostheses. But I already offered some rebuttals of that in a post on MentalScreen (http://groups.yahoo.com/group/Mentalscreen/message/80 ).Then how else? It all depends, I believe, on an understanding of the format of thoughts, of the medium in which the deductive ratiocinations take place. More about this in the near future.
