Clipper Side-step

How about this as a way to stump Clipper? Generate a dialog between you and a friend of no relevant consequence. Load this sound byte into your system as a AIFC file (sound bite, or byte) Encrypt data/message/information/recipe/whatever into the low-bits of the sound bite. Play message over Clipper-infested line to waiting system. [ Yes, you could just encrypt a message and send it, but in the above situation, fleas-on-the-line would not even know data was being transfered as they listened to Aunt Agnes talk about broccoli casserole. ] Just bouncing ideas...
