Good article.  I'm glad it works for you.  My current employer is about to start experimenting with it as our headquarters gets compressed into a single building.  My issues when I used to telecommute were

1) reduction in networking with other professionals in and out of the company (important with layoffs ever near)

2) loss of visibility to people besides my boss who still have an impact on my review/career (I don't blame my boss for this - it is a skill to be developed like any other)

3) my significant other could not accept the idea that just because I am home does not mean I am always interruptible.
