I got something roughly working but still some kinks to workout. It receives my messages from @White Noise but responds slow and then not at all.

It seems to be having problems with the "epoch" getting out of sync. I pretty much let my OpenCode + @PayPerQ coding agent write the whole thing.

I'll keep hacking on it when I have time, happy to get help from anyone else interested.

Is anyone working on something like this to talk to a Hermes agent?

First channel successfully created!

... and I finally got my ldk-server node up, and recklessly on mainnet! 🙌 Next step is setting up some channels and shuffling sats around.

Congrats ! Sounds like a great new project 🚀

Are you thinking total number of sats per US cents ? was only a matter of time. And all the sats aren't even mined yet!

This image is obviously photoshopped, one of those is a parallel cable and I do not see an accompanying dot matrix printer.

LTO-9 tape storage can sock away 18-45 TB per tape, depending on compression. So you'll need a pretty big filing cabinet or two.
