Then all the tools like 'netstat' and 'route' need modifying to talk to a
netgraph socket, but in principle I don't see why it couldn't be done.

ISTM there are a zillion userland-to-kernel and kernel-to-kernel
communication interfaces:
- ioctl
- geom
- cam
- netgraph
- vfs
- sysctl
- kmem
- procfs
- ...

Perhaps they could all be replaced by netgraph??

Brian.
