It would be nice to have an app that tested for $DISPLAY, and if present 
used [xg]message to pop up a notice about 'login denied' or otherwise 
just echo it to stderr and wait for a keypress.

Shouldn't be too hard to do up as a shell script....

In the end, though, that's closer to allowing the user to log in than I 
want to go. '/bin/false' users (usually daemons, etc) are unlikely to 
log in normally anyway.
