As I understand from looking at the code, there is a VNC server and a GDB server "running" on the machine already. These are probably provided by a virtual machine. VMware and Bochs both seem to support GDB-like debugging to some extent, and remote access through the VNC protocol. This package simply queries the screen via GDB, sends it off to SSH connections, and sends any keystrokes via VNC to the DOS machine. From the title I thought the SSH server runs directly on the DOS box, but as I understand, no Go code actually runs on the DOS machine.
