If we do meta-files as was originally intended, the command will be a
shell script could look something like this:

#!/bin/bash
read -sp 'passphrase: ' key
echo "$key" > "$0"/.../plugins/cryptocompress/key

The syntax of that echo command may change, but this is what we like
about metas -- less namespace fragmentation, less random interfaces.

Thank you, I was just about to say that.

There's a quote about this. Someone once asked Mohammed, "Should we tie
up the horses or trust in Allah?" Mohammed said, "Trust in Allah.
...But, tie up the horses."

It seems to be the custom of any list to just hit "reply-to-all". That
way, even if someone posted a reply after reading the archives or from a
forwarded mail, or even if they unsubscribe from the list, or even if
someone simply opened up their client and started a thread by mailing
linux-kernel@vger.kernel.org directly, or if someone just randomly adds
someone who might be interested to the CC list directly -- no matter
what, someone who's posted on a topic will see replies to that post
until the topic dies.

Of course, this isn't true of all lists. Some lists munge headers,
meaning that either "reply" or "reply-to-all" goes to the same place,
meaning no automatic CC's. I don't like that, because then it's harder
to take something off-list, and easier to accidently send something
supposedly private to the entire list.

If you take something off-list when you don't mean to, you can just
re-send it, but if you put something on-list when it was supposed to be
private, there isn't much you can do...

Of course, there's the annoying side-effect that if you are subscribed
to the list, you'll get lots of dupes, but so what? Bandwidth is cheap.
