> Beyond that, because when I first got a 30" monitor it was so much real estate and it took so long to move my mouse between windows, I wrote a little program that let me set and restore mouse positions with global hotkeys. It will also bring whichever window is under the mouse position to the front.

On Windows, the focus-follows-mouse feature does both these things. Along with raising and focusing whatever you mouseover, it also moves the mouse to any window you alt-tab too. Sadly, it's been tuned weirdly in new versions of windows so it isn't very useful now.
