CAN and Jaguars, any limits?

Reducing speed control messages where possible is a great idea, and I'm going to look into trying this.

In the case of our robot with 11 Jags on the bus however, we were seeing failures while the robot was initializing. In other words, some of the code was timing out when we first constructed the CANJaguar objects. The only traffic on the bus at this time should have been initial messages connecting to the Jags. No speed control yet.

Testing our terminating resistor is another avenue of attack, but in our case we saw the same problem on two entirely different configurations: our competition bot and also our experimental rig built from two other bots. I'm still at the same conclusion that ten CAN Jaguars is our maximum (at least when using the serial connector).
