This JS snippet (sorry for the broken formatting) works even in the - 
admittedly rare - case when people use a different shell than explorer.exe.  
Kiosk systems come to mind or developers that work on e.g. shell extensions 
and deliberately kill explorer.exe:

if (GetObject("winmgmts://./root/cimv2").ExecQuery("select UserName from 
Win32_ComputerSystem where not UserName is null").Count > 0)
  WScript.Echo("Someone's logged in");

Oh, users dig that sudden reboot when they have lots of unsaved data ;)
Seriously, not only can it often lead to unexpected behaviour even if all 
possible reboots have been inhibited...it also very much increases the need 
for reboot even when installing non-system software.  So yes, if you have any 
way to do so, get the users to log off before running WPKG.
