The proposal is to, effectively, do channel binding.  Channel binding
goes back a long time, to the early 90s at least (see RFC1508, for an
example from 1993).  I know of no patents covering the technique.  Not
that I would -- I don't go looking for patents.  But so you know,
there's plenty prior art, going back a fair number of years.
