Particular topics that need work
"tcp-thin"
A new feature in the Linux kernel: http://www.mjmwired.net/kernel/Documentation/networking/tcp-thin.txt. The goal seems to be to protect low-rate TCP connections with only the occasional packet from horrible performance when one of these few packets is lost.
BsdOSSpecific
Should be updated, preferably by someone with actual experience with such systems. In particular, the TCP socket buffer tuning hints from MacOSXOSSpecific probably work as-is on *BSD. Someone should check that, and either copy/paste the Mac instructions over to the BSD topic, or unify them somehow else.
