This seems like a great place to start:

Actually, your UserSpace would be what I call a "Session", though there 
is an overlap between the two ideas. Hmmm... I don't seem to have a web 
description of that anywhere.

But it is very simple - just think of sessions as separate VMs that 
have some shared memory but mostly communicate using messages. A 
special "boot session" has direct access to the hardware (or OS) and 
each logged in person has a separate "user session".

Very likely.

I started working on my design in 1984. It isn't simple to get it 
simple. Lately I have made progress by throwing things out, including 
cross space references (if you don't count proxies).
