Always a good idea, how often does the
screensaver kick in in a lengthy presentation? Always having to unlock the machine sucks. (Don't know how Haiku handles that ATM. Just saying.)
In the power management framework I have envisioned, the screen saving 
code would broadcast to applications that it is preparing to start,
and they could tell it not to start. So a presentation running in full screen would cancel the screen saver (along with media players playing 
videos, etc.) Actually all levels of power saving would have this, so
for example the machine would not try to shutdown the hard drive or go 
to sleep during a long download.
I think a proactive approach would be better, though. Ie. an app would just issue a command that prevents the screensaver from running. This should be made in a way that this is automatically reverted once the app is gone.
We have already discussed this and came to the conclusion that the way Ryan outlined above is the most elegant, flexible and most robust. Already for the reason that you mention "This should be made in a way that this is automatically reverted once the app is gone", the pro-active approach has more points of failure.
