Today I learned about the i2p project! Looking forward to trying this out. Sadly I have nothing to share to help answer, but thank you for raising your question

have you ran into any issues with the reconditioned drives? the thought has never set easy with me

I had no idea at all this was a service of theirs.

Any different from the other SoC options fire stick/roku/etc - mostly only that I don’t have any of those to play around with, but through work I do have access to cheap NUC Like PCs.

I have a Bluetooth kb& mouse connected to each. Spacebar to play/pause works everywhere.

Audio is mostly in sync, but if you’re in a place where you can hear both TVs at once there’s a delay you can hear. I’m walking around with a Bluetooth headset connected to a TV that’s physically in the middle of my house to keep the reception mostly good enough.

Is pihole alone enough to do the reverse proxy, or do you need caddy as well? I’m only somewhat familiar with how these things work
