I wrote "covert channel" too, when inviiting you to reply -- sorry about that, you're right that the side channel is the bigger worry.
(Will anything solve that problem, short of the kind of communication technology described in science fiction, e.g the phones in http://www.amazon.com/Dead-Lines-Bear-Greg/dp/0345448375 ?)

Leo does not concur and I suspect others (Arv) agree with him.
IMHO Leo's point about weak listener maps and FRP is a good challenge to the consensus that you, Erik Corry, and I among others do share. I need to read Greg Cooper's thesis and medidate on our myriad C++ weak listener use cases before replying further.
