Sugar's desired realtime collaboration experience can only be provided on top of a firm foundation -- a robust, efficient network stack designed to accommodate automated diagnosis and standardized workarounds. (Anything less just wastes teachers' and students' time and patience for spite.)

Sugar's desired realtime collaboration experience can only be provided atop a robust and efficient network stack designed to accommodate automated diagnosis and standardized workarounds -- anything less only wastes students' and teachers' time and patience, contrary to our human interface guidelines.

This unfinished essay summarizes an attempt to work out a simple way to realize this sort of network experience, with existing software and hardware, while also demonstrating the sort of thinking which might help other parts of the system achieve the same standard of quality.
