Disable screensaver via d-bus?

Is there a way to disable the screensaver via D-Bus? Because I use
Kaffeine-KDE3 (the KDE4 version still isn't quite as good), the
screensaver doesn't turn off when playing videos. I'm planning on
writing a little shell script that'll periodically poll Kaffeine's
status via DCOP and disable the screensaver if a video is playing. So,
how would I disable the screensaver via the command-line? (Presumably
using D-Bus, but I know, or at least I used to know, how to use D-Bus
over the command line).


Thanks,

Muzer.
