OpenOffice Impress compatible remotes?

[Matthew Gracie <matt@roadflares.org>]

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.

I thought that it would be a pretty platform-independent thing, but I 
just tried a (pricy!) Interlink model and it didn't work at all. I'd 
rather have confirmation from someone of a model that works before I 
drop fifty dollars or more on it.

Thanks for your help.
