If your concerned about bandwidth, you can fairly easily reduce the framerate and resolution of the camera.

We're using a netbook about the equivalent to the classmate and it works fine at 320x240 10fps (IIRC).

Regarding the auto aim, I was amazed to see how well our drivers were able to line up manually (we had some issues with our wifi bridge yesterday, so thats all we had). For our autoaim, I included a safeguard that prevented the operator from firing until we had a lock OR until he pressed a second button (as an override). We still have all our camera code in, but it's barely been used.
