"It has been mentioned that you should always use crypto. If you wait until you actually have something private to send, then an adversary will know exactly which message is important."
Or, alternatively, if Crypto use by "everyday folks" was as common as, saying, Gnutella file sharing, then it would be a HELL of a lot harder for invisible ears to pick out potentially interesting encrypted files (how many Gnutella files are shared each day?). And I wonder...with international companies now cracking down on "Power-Users" of networks like Gnutella, one would think that building-in some crypto capabilities (say into Kazaa) could be something "regular" people might be willing to pay for. (Or, at the very least, if the Kazaa crypto add-on itself became a shared file, why it would spread like wildfire!) TD
