     I think it was a mistake to introduce the concept of multiseat in 
this discussion. What matters is who has access to the shutdown button 
of the DM. Wether the DM exposes a button or traps a special username 
makes no difference.


     Note that the priviledge to shutdown a computer is not so big, 
compared to the priviledges one gets with the root password. On many 
servers, I give the shutdown priviledge to several users who ignore the 
root password - with sudo.


     In any case, any person who has the possibility to push the power 
button or cut the power cord should be given the opportunity to click 
the halt button instead. ctrl-alt-f1+ctrl-alt-del can  be used to 
reboot, but there's nothing to halt.
