I absolutely love this, and my mind's already buzzing with a bunch of ways I can use it. I love the simplicity, the docs, the pleasant experience of understanding and getting it running. (In like 10 seconds!) No logins, no user permissions management, no API keys and complicated auth creds, just a topic/password. So cool. I think it's cool for every once and awhile to push back against the trends for complication/over-engineering even if just to remind us of how simple/straightforward software can really be.

You've made a beautiful piece of software for your own enjoyment and the benefit of others. It is just what it needs to be. Bravo. In a world where projects get massively complicated and pumped full of VC funding, may efforts like this live on.
