Support lock screen message for owner information
Most OS, like Android, have a feature to display a static message on the lock/login screen, containing information for example about the owner, who can set a short message of any kind ("Office C6-01 laptop #1"/"Foo Bar's laptop"/"if lost write an email to xxx@yyy.com"/...). Something similar would come in handy in most cases, such as quick identification of devices and its owner in case of loss without needing to log in.
