You indicated that you were going to be writing your own module.
your module should include the interface functions indicated in 
ng_sample.c

That will allow your module to be hooked up to the other netgraph 
modules in whatever orrder you want, and that includes the ng_ksocket
module that would allow your module to sned and receive data through
the in-kernel socket.
