I would not make that assumption. We ran into a lot of issues trying to get compressed 640x480 images back to the robot. We ended up ditching streaming entirely and instead just grabbing a single frame for our targeting system this past year.

I agree 100% with this. That's why we have started down the road with the Tegra boards. Despite what FIRST says, FMS Lite != FMS. There are some oddities with FMS that only occur when you are on a field with full FMS and not in a lab.
