I haven't tried it, but I'm considering using Xournal[1] for this the
next time I have a chance.  Xournal allows you to load a PDF
"background" and mark on it with your mouse/stylus/whatever and have all
those annotations in another layer.  I use this extensively for marking
up documents that people send to me on my Nokia 770.  I think it'd work
for presentations also.  At the end of the day Xournal exports back to
PDF with the background and the annotations on top.

The only real downside for me is the fact that Xournal stores everything
as bitmaps.  Really should be vectored.  It doesn't support any type of
handwriting recognition either -- though I've never really wanted it.

I have no problem with this -- I find it's just a matter of getting used
to using the graphics tablets.  But, Xournal was designed more for
tablet computers, and works great on the 770.
