FYI- I will *** NOT *** be carrying this idea forward. If you like the idea, someone else will have to own it and drive it. My commuting days will end in 2011 so it doesn't make sense to even start a thread I can't participate in.
Because of the limitations of the forums, I'ld suggest using a separate post for each metal, that way you can vote more than once and generate interest for each metal.
Good luck and have fun riding.
