One-Wire sensor needed for barometric pressure and wind speed

Hi again, guys. I'm using the BS2pe to create an on-board weapon fire control system. An important part of that system should be able to sense wind speed (perpendicular to the direction the weapon is aimed), and barometric pressure, in order to tell the weapon operator how to adjust his scope. Naturally, all of the pins are used up - so I need to re-use the one I have the temperature sensor on which works with the one wire protocol. Anybody know of a pressure and wind speed sensor (solid state, not the rotating kind) that also works with the one wire protocol? Also, a one wire type tilt sensor would be great if you know anybody who makes one.
FYI - The equations needed to compute bullet trajectory require 9 situation dependent inputs (3 are temp, press, wind) and include fractional exponents and trig functions. Surprisingly, I was able to convert all of the equations into an algorithm that only requires 16 bit integer math - very nice
