  That's exactly what I do.  I turn on my emergency system every couple
of weeks, "emerge --sync" and "emerge --ask --deep --update --world",
run etc-update if necessary and then shut down.  I have a honking big
19" CRT on my desk at home, and the KVM is used elsewhere.  The machine
name is m450 (450 mhz PIII).  My main machine is m3000 (AMD64 3000+).
There is an ordinary user "waltdnes" on m450.  /etc/sudoers on m450
contains the following line...

waltdnes  m450 = (root) NOPASSWD: /sbin/poweroff

  I have a short script ~/bin/stopm450 on m3000 ...

#!/bin/bash
ssh waltdnes@m450 sudo /sbin/poweroff

  To shut down...
  1) via ssh shut down unnecessary programs on m450
  2) exit all ssh sessions to m450
  3) stopm450
