That's in large part the source of my skepticism. Not that it couldn't be done at all, but rather that it couldn't be done as seen on TV. <G>
I'm not claiming or insinuating that there's any metaphysical element to it, but the fact is that we really don't understand what consciousness is. We just don't know yet what makes us self aware. Given that, there's a real possibility that the first time you use a transporter will be the last thing you ever experience. What comes out at the other end will look like you, act like you and have all of your memories (but none of your experiences). He'll think he is you and everyone will accept him as you, but he won't BE you.
