Howabout starting it as a daemon (running as root) via the boot

Cool idea - you could even have multiple hosts connect this way but
export one DECNET endpoint, i.e. run CTERM on Box A whilst FAL goes to
Box B, and MAIL to Box C :)

Are you trying to suggest something like NAT for DECnet?
I'm not sure how easy that would be to do in DECnet, as it works in some
different ways than IP that might cause problems doing this.

Reading through things a little more...

Are you actually talking now about implementing a DECnet stack on a
machine in user mode?
That is definitely not doable.

Depending on the OS, it's perfectly doable. I wrote LAT for Linux in this exact way - because I didn't want to mess around inside the kernel.

It's not ideal, and performance will probably be awful, but if you can get access to raw ethernet packets it's not not even especially hard :)
