Why would you expect to be able to find them, any more than you
know whether or not your postal carrier reads your postcards? If
you send traffic anybody can read, surely it is no surprise that
you can't detect them reading it? It's startling that there are 
situations
in which one *can* detect sniffers, not that there are situations
in which one can't.
