Probably no need to wait that long really. Professional movie makeup artists
can already
do wonders and aided by a noisy video feed could probably even fool close
associates
if the conversations were kept short enough that the impostors' mannerisms
or
slips of the tongue didn't give them away. An impresionist could probably
even
dub the voice so that it was good enough to fool most people.
