electronic voting system

I need to build an electronic voting system to collect audience opinions (maybe using a radio frequency device) and pass the result to a pc for processing. Users should have a device with different buttons (2 or 9) and they should be queried by a master system on reception of PC command.
Does anyone have any reference for a project like this?
I had one from an italian magazine but they don't have the PIC software anymore so it's not use.

thanks in advance

Hmm... does it have to be wireless? And does the computer have to keep track of who voted for what? (I would think not.) Also, what do you mean by "2 or 8" buttons? I can help you if you give me that info. :wink: See ya.
