A VM that can be precisely described in 200 words? Does that include the IO subsystem? I have my doubts that it's possible to describe a full set of IO operations that any modern VM needs in so few words, just because of the wealth of features that you usually need (file system access, sockets (TCP and UDP), pipes, IPC, ...)
