"Should" according to what? Some principal of typographic purity? When I am designing Web pages for computer monitors, I virtually always want the underline to be a single pixel in thickness (especially when used for hyperlinks). Even if I wanted a bigger underline for larger letters (I never actually have, btw), I would want it to be an integer number of pixels thick.
As for position, I would much rather it be in a consistent position across different fonts or sizes on the same line.
