Matt, you must have missed a couple of posts, yes your suggestion:
stty -echo; ssh HOSTNAME "sudo some_command"; stty echo
did work but Marc Deslauriers pointed me at
https://wiki.ubuntu.com/SecurityTeam/FAQ#SSH where an even better
solution is to be found:

ssh -t <ip> sudo shutdown -h now

thanks

Colin
