However, with a shared database, if you have (for example) a tv episodic and you have a single project per episode, multiples operator can access the same database and work on multiples projects (one machine per project).
That should work also with the free version. (Not 100% sure if you need the studio to setup the shared environment)
You can only use Local Databases with the free version.
Maybe you can hack around this if only one machine is using the free version, by having the [PostgreSQL] database on the machine with the free version installed and then having other machines access it... But it won't be able to access an external database server for project management.
