That paper has been reviewed at one time or another by at least a dozen card-carrying physicists, including Jeff Kimble and John Preskill at Caltech (who are the ones who actually helped me figure all this stuff out).  Reactions range from, "Oh my God, what a revelation!" to "Duh.  Everybody already knows that."  But I have yet to encounter anyone who knows what they're doing who thinks it's wrong.
