A coworker sent me this article about Best Buy's ROWE (results only work environment). 

In summary employees come and go as they please.  They can work from wherever they want and whenever they want.  They are measured on their output vs. the number of hours they spend at work.

I think it's an interesting concept, but I'm not sure I'd do well.   I personally enjoy the social factor at work.  I also don't have hobbies and such that keep me from being in the office... you can't arrange flowers while working no matter where you're working from.
