Had we started

Where would networking be today if… Let’s go back to the beginning of Ethernet (to keep it simple). Imagine that many developers began developing their own networking schemes between close proximity machines, but that all the code above the driver line was user space loadable, performance wasn’t an issue and for the time being, no need to communicate over long distances. Assume Open Source and that developers had community coding tools like Github at their disposal.
