I strongly suspect that delivering them securely to the vast number
of endpoints involved and then securing the endpoints as well would
radically limit the usefulness. Note that it appears that even the
NSA generally prefers to compromise endpoints rather than attack

The problem these days is not that something like AES is not good
enough for our purposes. The problem is that we too often build a
reinforced steel door in a paper wall.
