DisplayLink grew from a back-of-the-envelope calculation (quite literally) where we realised that general-purpose networks were getting fast enough that they could be the connection between your computer and your monitor. The company’s current technology focuses on video-over-USB, but it had its origins in the ethernet-based ultra-thin-client hardware we developed for the Ndiyo project.

If you’d like to know more about the history, there was a keynote I gave at a conference in New Zealand in 2007, which explains how all these ideas link together.
DisplayLink continues to go from strength to strength: you can read more about what they are currently doing on their site.
