I'm not sure whether you will gain any real world speed benefit from lookup tables in this case, the Brown algorithm can be simplified heavily, if you only take first order (in our case barrel-) distortion into account. And even including second order distortion is no challenge for modern graphics hardware. But if you are really after the fastest possible solution or just want to do it for the fun of it, why not? Sounds good to me.
