“I just setup an Apache web server for use at home, and now I’ve got 4 Apache developers living in my basement. When they showed up, they said they were my Apache community overhead and I had to let them stay there. Oh, and I apparently have to feed them too!”

You do not need to feed them. If the demand for food is strong enough somebody will volunteer.
