You'd have to have a pretty big kitchen to use. I do know of a couple of people who do cooking co-ops. One is just two families who are neighbors, and once a week they cook twice as much food and take it across the street. (they trade off.) The other is a co-op that's more formal - I think it's 4 or 5 families, and they show up with all of the food already cooked and divided into family-sized portions. So you would make chili, for example, and divide it into 4 containers and bring it to the monthly get-together, and everyone would go home with 4 different dishes to freeze.
And of course I've done cookie baking get-togethers at the holidays. Fun!
