Well, at the QA job i don't have anymore, We were able to do all our work (as a QA Lead), wirelessly, anywhere. As long as we had two things: our work laptop, and a mobile device of some kind to load versions onto.
We'd monitor and "participate" in office life by at least 3 methods: Skype chatrooms, email, and a business-oriented form of Facebook whose name slips my mind at the moment, and some might say also Facebook.
all of these just need a wireless connection, that could be anywhere.
our QA work itself consisted of: writing emails, reading emails, leading a group of off-site testers over Skype, finding and writing up bugs in the game.
Our bosses tried to keep us in the office through carrot and stick. There were delicious lunches every day. There were also weekly "all hands meetings" where an increasing number of us crowded into the main office. But i think the office wanted to be distributed.
I'd argue that the place i worked was a distributed office even as it tried to be a regular office. A transitional form.
