Hi Alan: You're right, TinyEMU Emulator talks to a WebSocket VPN hosted at ` relay.widgetry.org` that's throttled at 40 kB/s (for free, fair use). But I don't see a good alternative to this WebSocket VPN: (1) Can the Web Browser talk directly to the internet without WebSocket VPN? TinyEMU and VirtIO Networking are sending Ethernet Frames / IP Packets from the Web Browser to the internet. But Web Browsers are not allowed to send IP Packets directly. That's why we need to tunnel the packets through a WebSocket VPN. (2) Can we host our own WebSocket VPN on our Local Computer? Possibly. But then we will have to host the Web Server on our Local Computer too. Which makes it cumbersome to install. (3) Can we host the WebSocket VPN on a server operated by the NuttX Project? Probably not, because we need to throttle the internet traffic for free, fair use. And prevent abuse. I've documented my findings on TinyEMU, VirtIO Networking and WebSocket VPN: https://github.com/lupyuen/nuttx-tinyemu#tinyemu-networking-in-the-web-browser Lup On Sun, Jan 14, 2024 at 9:54 PM Alan C.
