You were all very helpful. I think we're going to wait until kickoff to see exactly what type of vision processing is required (more simple, or more complex).

However, I'm really liking RoboRealm and the Labview vision solutions. As for latency (again, depending on the challenge), we might just have a button on the joystick that will "auto-aim" (process the single frame), rather than constantly processing.

I would still really like to hear a bit about OpenCV, but I'm getting the feeling that it will be a bit more complicated. Has anyone used a Raspi and the USB interface to transfer the data to the RoboRIO? (Preferably with LabView). I'm not sure how you would ready from the RoboRIO's USB port.

It's not a Raspberry Pi but close enough: http://www.chiefdelphi.com/media/papers/3147

There a quite a few papers talking about similar solutions:

I would not use USB to transfer data. You're going to end up having to emulate another device to get that to work correctly though it's an interesting thought. USB is really meant for peripherals and not co-processors. Ethernet or one of the myriad of serial interfaces would be better.
