Using two cameras without exceeding bandwidth limits?

[xraymypanda]

Does anyone know how we would be able to use two cameras without exceeding the 7Mb/s limit? Last year we used two cameras on our robot but ended up removing one of the cameras because we were managing to use way too much bandwidth at the time when there was no limit. Now we are stumped but we would love to have one camera on our disc intake and another on our shooter. I've considered having a switch that changes which camera is initialized at a time but worry that this will cause the camera to have to reboot every time we switch?
