There is a Google Edu talk from 2006 from the founders of Second Life where they mention how SL wouldn't have existed if it wasn't for cable modems.
Why?
Because SL did all physics rendering server side and then streamed the view to the client's PC. This wouldn't have worked with dial up.

- dale_glass 3y agoSecond Life's spiritual successor, High Fidelity (now dead as a commercial project, but which lives in our open source fork overte.org) does something like that. The server picks a client to do the physics for part of the world. It's pretty clever and means a very light server can go a long way, but the downside is that physics gets unreliable. One of our plans is to have an option for a SL-like model where the server is again in charge, for scenarios that require security, reliability, or physics to keep running in the absence of clients.
