Could you build this?

Partial Wrapping the open-source v86 x86 emulator in a web UI is simple, but compiling a customized lightweight Linux/Emacs image and configuring WebAssembly emulation with terminal IO requires specific systems knowledge.

What it would actually take: Uses the `v86` WebAssembly PC emulator embedded inside a web page with Xterm.js or canvas rendering. The challenging part is preparing and stripping a bootable Linux kernel and root filesystem image with Emacs pre-installed to minimize bundle download size, configure virtual terminal serial ports, and handle filesystem persistence via IndexedDB.
