The NLS demo wasn't networked; it was based on time-sharing with terminals. But in his closing statements, Engelbart mentioned SRI's upcoming involvement in an experimental network project at ARPA, which he predicted would grow to a nationwide network of 20 computers that would transmit data across the country at 20Kbps.
