Yes. I think the only really solution for this has to use X, so that only 
users with access to a display can change the screensaver settings for that
display.

As far as I understand the xlib's screen saver functions (described in 
chapter "9.7. Controlling the Screen Saver" of
/usr/share/doc/xspecs/xlib.txt.gz) and the DPMS extension (described in
/usr/share/doc/xspecs/xlib/DPMS.txt.gz) could be used for this.
