i think what's called for is a vdd of some kind, similar to the virtual 
ethernet and virtual disk drivers. yes, it would appear in the guest at 
the vfs layer. i'm surprised that the qemu community doesn't already 
have it.

this is something virtualbox gets wrong, by the way. it offers something 
that sounds like what i want, but then implements it as SMB.

don't get be wrong -- UFS and NFS work for me, and i love bhyve as-is.
