Yes, there would need to be some extra stuff. Here are some
quick possibilities..
- We'd need to enhace the definition of a netgraph address
to include, say, an IP address, eg.:
$ ngctl msg 192.168.1.12:foo: blah blah
- Encode control messsages in their ASCII forms for transit
across the network
- Pick a well known UDP port to be used for netgraph messages
and data packets
- Create a node type that could listen on this port (using ng_ksocket)
and do the required encoding/decoding.
