Seeing the list, now I'm sure which BSD that SCC likely used in their Sidewinder firewall. They modified it to have mandatory access controls to contain breaches of subsystems. This was before SELinux, etc. Never used BSDi, though, so can't say much about it except its users were getting pretty of mileage out of it given rep of products based on it. Least in appliances.
