I've seen it used in production by larger orgs. The scale where you plan for around 6 months of migration, customization and integration of your legacy zoo with 7 different user account DBs. On one hand, all of these projects were successful and now run it in production. On the other, they all really needed the 6 months to whip it into shape.

Edit: Meaning I would use it if you need to get up and running quickly, but it's a solid foundation to build on long-term.
