I think "everything is a file" also means: everything is addressable by a file path. Per-process namespaces are part of what makes this possible.

In a way it's similar to HTTP REST, which is also organized by file paths, except instead of the HTTP verbs GET, POST etc. you get open, read, write as your verbs.

A side channel is then just a directory entry.
