Hm. TIL Inferno; I read but I still don't feel like I understand it. What I was talking about was a little bit more of a browser-native "OS" shell if you want to call it that... I feel like the kind of ease of interaction that people have on the command line on a Unix system still doesn't really exist for any type of web resource that I'm interacting with. It's all separate systems without much unifying access or principle.

Maybe Inferno would have been the answer (like I say I read a little bit still don't really grasp it), but the WP page seems to say that Lucent didn't really have a coherent way to deploy or market it and so even it being a good idea wouldn't really have saved it from obscurity. :-( Like I say it is sad overall, these things were better than the stuff we have around now.
