All forms of communication are bootstrapped by first determining if you
are the intended receiver. Making the receiver initiate that process
only relabels the endpoints; the receiver now needs to initiate
communication with new parties. The net result is that senders can no
longer reach any new parties. That's a very uninteresting network, IMO.

That'd be interesting only if it could show how to initiate
communication with a new party without reversing the labels.
