Science fiction authors of the future of Mars should keep this in mind.
“Interplanetary communication is greatly delayed by interplanetary distances, so a new set of protocols and technology that are tolerant to large delays and errors are required. The interplanetary Internet is a store and forward network of internets that is often disconnected, has a wireless backbone fraught with error-prone links and delays ranging from tens of minutes to even hours, even when there is a connection.”
There were even stories written over wars fought between inner planets (with financial markets) and e.g. Pluto who was always behind in stock trading etc and at a financial disadvantage.
The Pluto-war story might have been part of a series, that's all I remember.
