netconsole?

Trying my Seagate Dockstar, I wondered...

we don't have anything like Linux' netconsole?

(console output sent away via udp to configurable server UDP port
6666, console input received on same port, UDP over IPv4 sent with
a preconfigured MAC to work before ARP is set up. console output
(and input) can be handled by a (pair of) netcat process(es).

Unfortunately, I'd need to proxy install, or to open it and connect
a 3.3V serial adapter ... but see below.
