George,

I believe netstat already utilizes the sysctl API to get information about 
the TCP and UDP control blocks for state information. The modules for tcp 
and udp already contain sysctl backend routines that do this. Additionally, 
there is implementation for the ip_divertlist and the raw CBs as well.

Are you referring to something in addition to these?
