I find that the people who supposedly want everyone to work on site will always make exceptions if it means getting an employee they really want. You know that if <Insert your favorite programming blogger here> offered to work for you, but only if they could work from home, you'd probably make an exception. If the person who's been your rock star coder for the past couple years needed to move away for family reasons, but would be willing to stay on if they could work remotely, you would make an exception. The side effect is that you are now telling all the regular people who show up to the office every day that they are not as valuable as Mr. Works Remotely. How do you justify having potential new hires relocate to work for you when they find out some special people don't have to go through that?
