I'm putting together a talent show and would like audience members to
vote for performers using keypads. I think I need a bunch of infrared
transmitters/keypads, a receiver, a computer, and some software. Does
anyone have an idea where I can get the keypads and put together such a
system inexpensively? Thanks for any info.

NS IR will suck. Use RF.

Thinking about a bunch of RF transmitters all heterodyning in the same
room, shades of Theremin!
