Might be cheaper & easier to just set up an old desktop/laptop w/Ubuntu
close to the projector as a 'projector server' + hub/switch and then
just connect to that via long ethernet cable. You could do the same via
wifi, but that will cost more than a 50/100' ethernet cable will. Set up
NX or freeNX on both systems & then just NX into the projector machine
to run your presentations.
