Look at Arduino, or Create USB Interface.
both are relatively cheap CV-to-USB interfaces.
The first shows up as a serial device, the second as HID device.
HID can be used directly in Chuck, afaik. Serial I don't know.
There are also other programs which can deal with either, like SC or Pd.

camera-based solutions are cumbersome if they get too dependent on light 
levels in the room, as they may vary per performance. Depending on the design 
of how you use the signal, this may or may not be a problem.

What about a microphone in the audience area?
What about piezo's under the seats (depending on the concert context).

I suggest looking at the NIME (www.nime.org) conference proceedings to get an 
overview on what people have done in this field, and what is out there.
