Wired has an article on a company that use a coffee house as their office:

Delicious Monster is the Mac software company behind the hit Delicious Library, a program for cataloging collections of books, movies and games. The software is selling like hot cakes and has garnered rave reviews and awards, yet the company’s headquarters is a Seattle coffee house.

As well as creamy lattes, the coffee shop offers wireless internet access and big, bench-like tables that several people can gather around. Often, Delicious Monster’s entire seven-person staff will work there.

“Zoka is pretty much their office,” said Reid Hickman, a Zoka barista. “It’s a pretty good deal. They hang out here all day and they often get lunch and dinner here. They take good care of us.”

This is yet another interesting blurring of what is and isn’t work. Or of where work can or can’t be performed. Expect more of this kind of thing.
