In reality, this was an attempt to turn Plan 9 into a commercial product.<p>Plan 9 despite it's crazy UI (the shell and editor have been ported to Linux so some people must have liked it) brought a lot of new ideas which eventually found their way into other projects such as Linux containers and Go (for obvious reasons).<p>One <i>really</i> good idea that died with Plan 9 was transparent distribution of CPUs across the network. You could - the same way you mount a network drive today - mount a remote CPU and run your local software on it.
