If you've got any ideas for what a multi-subscriber interface would look
like, I'm happy look at it. I don't think there's an especially
compelling use-case for one right now so I'm not enthusiastic about the
additional complexity that'd be required, but as long as there's basic
agreement that it's not practical to do this in userspace then we're at
least on the same page.
