One item of note Sam mentioned in his Rotor BOF summary
One thing I encourage people to do is look at Rotor on FreeBSD 5.1 the latest and help with any porting issues.
Since I started working with FreeBSD 4.8, I have also been receiving the latest versions, including FreeBSD 5.1. I will also install Rotor on this version and let everyone know my test results. I am also interested in helping with porting issues as I have been doing with Andrew regarding Rotor on RedHat Linux 8/9.
