I sense a misunderstanding here, why would the machine switch runlevels 
when users log on/off? On most linux distributions, runlevel 5 is 
defined as "runlevel 3 + graphical login".

So, if you want all logins to go through the GUI, you leave the machine 
running at runlevel 5. If you want all users to have the normal text 
login, you leave the machine running at runlevel 3.

Changing runlevels while users are logged on is unrealistic, since a 
killall signal is sent whenever a runlevel change is performed. Think 
of such a change as a soft reboot - it's not something you want to do 
on a running machine, and can be performed only by root anyway. There 
is no usable system "during" a runlevel change, all processes (except 
init I guess) are killed and then the start scripts of the new runlevel 
are executed. (at least that's the proper way of doing it, it wouldn't 
surprise me if Red Hat does things its way)

Just set the talk daemon (and any supporting daemons like xinetd I 
guess) to start in the runlevel you're going to use from now on, and 
you'll be fine.
