Well, it doesn't have to be possible. Instead it should be possible to have the mount(2) syscall detect the loopback NFS and convert it into a lofs mount if, say, a flag is set in the arguments, or even by default. That would work transparently for the automounter. Though it the automounter were not calling mount(2) directly, but instead passing back mount info to the autofs kernel module caller (which it does for some fs types), then the autofs module would need to know how to convert the mount to a lofs mount.
