Currently I would probably be the overall manager for any that I'm involved in, but it could be anyone as long as they have the skills. And the manager is mostly just making sure the whole system keeps working well, while individual monitors (everyone is a monitor) are the ones most directly keeping people on task.
It sounds complicated, but it sort of takes the approach of "everything should be a simple as possible, but no simpler." It just has enough indirectness to make it much less susceptible to "death spirals."
It differs from working for "the man" because you still decide what projects you want to work on and so forth. You are working for yourself, but the system (manager/monitors) is helping you keep on task in ways you have already decided you want to do.
Really, the manager can be considered an agent of your long term interests (i.e. your desire to finish your projects and otherwise get things done), helping you defeat your short term interests (which might be your love of sleeping in, watching TV or playing video games, or whatever it is you do when you procrastinate).
Get in touch if you want to join. I've got a few people but we could use a few more. We are starting a new group since I've sort of spun off the old one
