It's this sort of thing that when I first saw it on Apollo's Aegis and again later on Plan 9 it was so obviously useful I figured it would just be everywhere in no time. At then Sun touted "The Network Is The Computer (TM)" and I was like here it comes! But it hasn't quite panned out that way. Considering the number of viruses and ransomware perhaps that's a good thing but it would be cool as hell if I had shared name spaces with my wife, mother, sister, etc rather than the artificial constraint of mapping into Facebook or Google Photos (for example) to share a photo album.
