Comment:

 See Yawning's experimental results at
 https://lists.torproject.org/pipermail/tor-dev/2015-March/008485.html : it
 seems that LIONESS is going to be a heck of a lot slower than we can
 accept.

 Hope is on the way, perhaps: DJB and Rogaway both tell me that AEZ is
 probably fast enough and secure enough. (Especially if we're willing to
 depend on AESNI.)  DJB says that he's got a more generic construction in
 the works that doesn't rely on the AES round function, and if that's done
 soon enough, we can consider that one too.
