The web server interface for Mileage, tach, avg tach and/or speed, and maybe even mpg probably wouldn't be impossible (though the mpg would take a bit of playing, as it would require some sort of sensor to detect how much gas was going through the lines) if, again, I could find something to detect the speed of the cables.   I know you can get some with magnetic pickups, but much more efficient if you can use what is already there.

You could probably even make it so people could connect wirelessly to it to check it out.

Having it controll the ride would certainly be possible, but the customizing of the gyros and motors involved is a little above my realm of experience.
