networking ... was tacked on later.

And rather badly at that. I'd like to know what BBN's reference implementation system calls looked like.

If you can read past the ALL CAPS, RFC681 describes the rather peculiar
open()/close()-in-userpace /dev/net/$hostname scheme they used back then.

A shame it's not still in use.

GNU awk can do this too. But it's not really in the filesystem, so it's cheating.

Of course, with FUSE and asynchronous name lookup, we can do this properly, without relying on a horrible userspace-NFS-server hack. (ls(1) would necessarily only be able to show you names you'd already looked up, though.)

Doesn't Plan 9 have a similar TCP-by-filesystem thing going on?
