Hi Benoît,

No, I've gone off to work on a initial proof-of-concept implementation 
of a qemu-lio-tcmu.so module, hopefully it'll be ready to look at 
shortly and then we can shoot arrows at it. :)

But in the meantime, do you have a use case or user story for the QMP 
support that might help me understand better how it might all fit together?
