    *But* unless you want to invoke Penrose that there is something
    significant going on at the quantum level -- then from a
    biological standpoint it seems *highly* unlikely that there
    will be a problem so long as I reassemble the copy with
    most of the atoms in their same locations.

    They should *not* have to be the same atoms (pointing out
    a problem with one of Lee's "levels") but allows teleporting
    to be an information transmission problem and not a matter
    transmission problem (which gets more expensive). Now
    the problem does arise that the atomic structure of the
    human body is a *large* amount of information -- I've
    never done the calculation but I strongly suspect that
    even using wavelength-division multiplexing on a fiber
    cable (or a bunch of fiber cables) it is still going
    to take you a *LONG* time to send the data content
    (and don't even begin to talk about radio transmission
    or you will have me ROTFL). So there *WILL* need to
    be data compression -- and I suspect some of it will
    be like JPEG compression -- lossy. So there becomes
    an interesting set of tradeoffs with cloning/teleporting --
    you can get there fast but you may not really be yourself
    or you can take the slow boat to your destination and
    have missed the party by the time you arrive.
