I used to use those interchangeably until I met up with the Associated Press Style Guide when I had that America's Cup job. It said I had to use "farther" for actual physical distance, and "further" for metaphorical distance. After having to refer to AP Style for everything I wrote for six months, I find myself using all its verdicts in conversation now too. Oh well.
