[libvirt-users] spice session locking

Hi List, Is it possible to prevent other clients from stealing my libvirtd hosted spice session? This is a problem for me where multiple co-workers access the same guest over a qemu+ssh:// connection. Instead of simply disconnecting clients, I'd like libvirtd to deny the new client. I've been looking at polkit acl rules and the vnc sharePolicy attribute but so far no luck.
