I think "different command line" is a big thing which is why we've spent so much time on it. But if you mean other end user features, no, we don't add anything new on the table right now. I think our userspace networking implementation is better than QEMU's slirp but that's purely technical thing. I also don't think we should add new features for their own sake. Linux virtualization isn't a terribly difficult thing to do thanks to KVM and virtio drivers. I think most of the big ticket items will be doing things like improving guest isolation and making guests more accessible to the host.
