Sounds good. I remember seeing bright colored shirts with "Trail Spotter" or "Trail Leader" printed on them for sale somewhere.
I think this is a good idea. The only constructive things regarding spotting I would add might be:
-Make sure there is only one spotter per obstacle, or as in the video, for specific sections of the trail. This helps the driver to focus on one voice, eliminating confusion/stress/and hopefully mistakes. Too many voices creates confusion, and the spotter up front will make the call as he sees it from the best vantage point.
-Resist the urge to say "straight," or "straighten it up." When a driver is going through and obstacle, correcting his steering by stating "passenger" or "driver" is much more efficient. You are the spotter, put his wheels where you want them with your voice. Most of the time drivers don't have the time or orientation to know where "straight" is on their wheels. Let the driver know before he enters the obstacle what set of hand signals you will be using so he is familiar with this.
-Use a calm voice, and resist the urge to yell or shout. Running obstacles can be stressful, and a calm voice and demeanor helps tremendously. There should be an unspoken trust developed between drivers/spotters.
-Make eye contact with the driver from time to time, so you know they are listening. Introduce yourself at the trail head or before the obstacle, so you can use their name. Helps to get someones attention when they hear their name. (and a good way to make friends)
-Only spot from the front of the vehicle. This is a safety thing pure and simple. People should never walk around a moving vehicle as it goes through an obstacle. Spectate and resist the urge to spot call from the sidelines.
-Spotters should wear good shoes, preferably lugged soled hiking boots. Low tops for comfort and cool (both style and temperature) are good options. Often you will be walking backwards and sometimes quickly over slick rock and sandy slippery surfaces. I have fallen on my butt more than once (to the delight of the crowd) when slipping while spotting in Moab and Big Bear.
-Wear a specific colored shirt or hat to make yourself easily identifiable.

Just a few ideas...feel free to elaborate and debate.
