On the roborio, it would work with Lifecam. However, I moved to the RPi using the instructions from the GRIP wiki and a lot of my own discovery. I need to post everything, but haven't had the time. Bottom line - it works pretty well on the Pi. I have not actually tested connecting to a USB Cam - I just assumed the instructions were correct that GRIP on the Pi does not work with USB cams. I set up the mjpg-streamer and configured GRIP to connect to port 5800 (I configured the streamer to stream on 5800, not 1180 like the instructions say because the publish module in GRIP publishes on 1180 and creates a conflict). You can use v4l2-ctl to adjust all of the camera settings - lots of control and it does it on the fly, without having to stop the stream. This means I can look at the stream in a browser and adjust the settings exactly as needed. I have some improvements to make - I would like to get the USB cam working because I'd like to eliminate the lag of the streamer. That's a summary - if you have any specific questions, post them and I'll try to answer them.
