No, I was merely thinking out loud - I think that the Overo should ship in a safe configuration that is rated for many years of use, but should someone need more performance, you're still looking at over 5 years of continuous reliable service.
Putting an Overo in, for example, an automotive application where the lifespan of the vehicle (hopefully) a lot longer than 5 years and you'd want it to be running at the stock speed, but if it's for a consumer application with a design lifespan of 3-4 years (of 24-7 operation, mind you) then you should be good to ramp up the speed to max...
