Jeez the offseason is TOO LONG. Killing me. Come on baseball!!!

So Neyer had a short article on ESPN today about VORP. I showed it to a non-saberfriendly pal. His biggest question was: OK, so how well does Joe Mauer do if you move him to first base?

Is there a VORP calculator out there? Is the formula and the numbers needed readily available? And can you apply a conversion to a VORP score directly, or do you need to recalculate from the start?

If someone has this or an excel sheet that will do it, I'd love to play with it - if not, then if someone can point me to the formulas and data, I might build something myself.
