> "Explain the original DERP protocol by Tailscale, focusing on its functionality and limitations. Discuss how Iroh has adapted and enhanced the DERP protocol, emphasizing the use of DERP URLs instead of regions."

and so on for the rest of their FAQ page

PS: Is keet.io a reincarnation of Cabal chat (https://cabal.chat/)?
