At times, I have considered putting some sort of tamper-proof timer switch on the DSL (previously satellite) line. I am on-line, or at least at the computer far more than is healthy.
However, since I work from my own place out in the boonies, I can stand up and in ten seconds be in the greenhouse or out on the farm or in the woods. It sure beats a cubicle maze. All the tools aren't quite there yet, but the internet lets me work in organizations that are hundreds or thousands of miles away. Sometimes I'm more in touch with people in Madrid or Houston than I used to be with people in the next room in an office building.
Once, I had some business with a publisher in Manhattan. I'd go out of my way to make contact before breakfast, because of the three-time zone difference. After a week, I finally found out that the editor who I was working with was actually sitting in a cabin, not ten miles from me! We logged off and met for lunch.
In fact... that sounds like a good idea right now.
