What I find so interesting about this is that it's NOT your co-workers. Which is actually really intriguing. I wouldn't be able to participate in this right now due to my living situation, but I love the idea.

One problem with trying to get co-workers to do this is that it's probably hard to find people that would want to. So instead open it up to a global pool of people and you're much more likely to easily find 9 that want to sit and work.

Long time ago I rented a co-working space for $99 / month and working amongst strangers is oddly powerfully motivating.
