Hi,

Agree that memory device and shared memory is incompatible.

But memory balloon device, I don't know if it's possible to use in 
future. As far as I can imagine: a user process runs virtio-of target by 
listening localhost, and memory balloon isolates same pages from kernel, 
the user process maps these physical pages into virtual memory ...
