Yeah, I think this is the biggest hurdle against (a)BUSE.  Is it
sufficiently different from nbd?  nbd-like functionality can be
implemented something via FUSE and maybe it can be said that things
are cleaner that way but nbd has been in the kernel for a long time
now and it's definitely much easier to do swap over it when the whole
thing is in kernel.

Thanks.
