I could be wrong, but I don't think axolotl signs the long-term DH key
or uses signatures at all. But the problem I'm trying to solve is
bootstrapping from a signature key (which already exists for other
purposes) to deniable authentication.
However, I agree that if the solution I've described works, it's very
much like axolotl with the addition of a signature over the long-term
public DH key.
