I thought that OpenOffice file format was open... but PowerPoint file
format is clearly proprietary. I also dislike that. Unfortunately,
OpenOffice can export it's presentation in SVG format, but not
PowerPoint. I don't see how we could do differently for the moment. I
think it will end-up in a first version using the sxi and ppt formats,
and a second version one day when there will be a more universal format
used by the major office suites...

I didn't think about that because our teachers at school never use their
mouse pointer for this purpose. Usually, they use animations when they
want to attract our attention to one place on the screen.
