Google Chrome

It's using many of the concepts I expored in my talk about the Amorphous OS, I will have put those slides back on the internet.

A big part is no local files.

Looks like it's build on a stock Linux Kernel.. I was thinking about this and they need to get ride of the paradigm of a process and replace it. 
Processes have there own time slices and memory.  They seems to have spend a lot of effort to give each browser tab it's own process, and in some circumstances they could not.

What they need to do it get rid of the whole concept and go with an object based memory model.

Where some objects are shared between processes where processes are not sandboxed memory as much as just time slices and sandboxed memory objects associated with parent objects.
