One more question: I have discovered a bunch of FreeBSD majordomo discussion groups on the FreeBSD web site. Can you recommend to me a discussion group that I could join where I could pursue this topic? I feel that difficult problems that promise great rewards deserve to be studied. Remember that I am relatively new to FreeBSD and especially to kernel hacking, however, I have 30+ years programming experience, and I hate malicious hackers.
