We're running X11R4 on DECstations (Ultrix 3.1d) and using XDM to log people
in.  We have a program (not an X client) that we want only the person logged 
in at the console to be able to run.  But unlike login, XDM doesn't change the 
ownership of /dev/console to the person currently logged in.  So you can't stat
/dev/console and get the person logged in.

How can you tell if the person running your program is logged in at the 
console?

Thanks.
