ssh is safer and it is handy also in places where you don't need security.
Good question I didn't ask myself, but I assume it would make no difference in the current situation: graphical apps can't open the display and do abort. You could test it youself:

1) 'ifconfig' to determine your IP address
2) export DISPLAY=IP address:0.0 (192.168.1.10:0.0 for example)
3) 'xclock' returns Error: Can't open display: ...

Any idea?

TIA,

You are looking for the setting nolisten tcp in the file /etc/kde3/kdm/Xservers if you are doing this in KDE.

[edit]
You would have to restart kdm for the changes to take effect with /etc/init.d/kdm restart as root this best done from a console login unless you want to lose any unsaved work when KDE re-starts.
