We pronounce the constant as pee in German anyway. (No confusion with bodily fluids there.)
Or we might as well go with dvapee (Russian), or tsveypee (German (zweipi, written so that you can pronounce it the English way and it'll come out ok)).
We can go for pronouncing the thingy pipi. (Though would lead to confusion with bodily fluids in German.)
Do you also favor the almighty interrobang‽
