Just to correct one point - the banners are still seen as part of the
stream of bytes by both ends. The option communicates a single bit,
out of band, to both ends. I think that's the problem.

So it looks like the concenous for this is pretty thin.

(Un)fortunately, I'm persistant as hell, so I shall consider what
other avenues I have. I still firmly believe that a world with
opportunistic encryption would be a better world than we have now.

Cheers all,
