Presentation Remotes for OpenOffice Impress?

saintlupus asks: "I'm going to be teaching an introductory Computer Science class in the fall, and I'm using OpenOffice Impress on my Debian Powerbook for a lot of the lecture material. Does anyone know of a brand of wireless remote that works with this presentation software? I'd rather not be locked behind the podium while I'm teaching, so the idea of a remote is appealing, but nobody lists Linux compatibility for these things."
