Like I said, this museum didn't exist when I was there at the end of 2008. It's only been created in the last year or two. As an employee, I had to go through a security check at a vehicle stop point to gain access to the Festool grounds and then needed a security badge to enter buildings and specific sections of buildings. The museum is currently in a space that I wouldn't describe as a good place to host guests.
I could definitely see this becoming something accessible to the public at some point. I just don't know when. So, hang tight. If I hear anything, I'll let you know.
