"...but hasn't been used much due to the cost and difficulty involved in forging a millimeter-wave signal, encoding information on it, and then decoding at the other end."
No, it has nothing to do with the encoding and decoding. That is the easy part. All sorts of algorithms already exist for that, e.g. DSSS and OFDM(A).
"Forging" the signal as you call it is the hardest part because test equipment and manufacturing costs for anything above Ka band becomes orders of magnitude more expensive. -- "We will add your biological and technological distinctiveness to our own.
