Hi Peter,

There is work done on OMEMO by Conversations team, which is XMPP version of 
axolotl. There has been a protoXEP, but it has not yet official number because 
it's currently depending on copyleft library (if I'm not mistaken). Daniel 
Gultsh from Conversations has recently announced that OMEMO has been audited.

Gajim has also an implementation, for now it's the 2 only ones (to my 
knowledge), but other clients are planing to do implementation.
