Is telecommuting really that desirable? At my previous job, I probably could have done it fairly often. At my current one, not quite as much (as Im meant to be managing people).
But I find home every bit as distraction filled as the office, don't have a long commute to get to work, and even if management were 100% on board, never being in the office has a social effect on how coworkers perceive you. Also, work time and personal time tend to blend inconveniently together more once I'm already at home and set up. So to me, part of the question is "even if you can telecommute, SHOULD you?".
I recognize that all cases are different, but for me, its really not something I'd ever fight for.
