As far as I'm concerned, RBS only works under SQL Server or SQL Express. As I mention above the application will use a Firebird database running in a Linux box. How can I add RBS features to this project? Any ideas are welcome.

Thanks, Marcelo.

The "All Projects" permission would be assigned to users who have access to all projects. In your situation, I'm guessing this would be to users who work at the main branch and either oversee, report on or provide some kind of support to any branch that needs it. In my case, it is assigned to a few corporate level consultants that have access to all projects and can provide support to consultant that needs it.
