I haven´t done it so far, but just a guess to the solution (I hope):

<smbstatus> gives you the name of the client-machines like

What about piping this output to a script or something else, extract the
machine name and then echo "Shutdown in 10 min!" | smbclient -M
<machine_name> ???

If you got the solution - I would be interested in a copy. Thanks.
