Yeah, compared to loopback over FUSE, anything would have less
problem. :-) I don't know much about nbd but it's pretty much solving
the same problem so I think it's logical to extend nbd including
giving it a new transport if necessary? Or is there something
fundamentally better when it's done via FUSE?

Thanks.
