Thanks to some great help from Eric Wendelin, I was able to finish
putting together a Google Quick Search Box plugin for Remember the
Milk.
I have open-sourced the Python segment of the code (the rest is simply
the applescript that launches it) here:

It's pretty slow right now. If people want to fix any of my shoddy
code, feel free.
