I tried two different solutions:
1. Add a user called shutdown and use vipw to change his shell from
/bin/sh to /sbin/halt. Use vipw to change the user ID to 0
2. Use chmod +x /sbin/shutdown to allow ordinary users execute
privilege.

Solution 1 might allow users to Control-C their way to a root prompt.
Solution 2 seems best to me.

Anyone see any problems with solution 2 ??

Unix systems measure "uptime" in years, Winblows measures it in minutes.
