In Mungi we are definately pursuing fine-grained decomposition. (At least I believe we are, others may have a different definition of fine-grained though ;).
And of course as Volkmar has mentioned that is the aim of the Sawmill project too. Or are you talking more fine grained than that?
I'm thinking of environments in which single applications are divided into multiple protection domains for reasons of robustness and recovery. In such a design, sender-id != application-id, and it is important that this distinction be efficient.
The last time I looked, the Sawmill effort was still working on separating drivers out of the kernel. This, in my opinion, was necessary but was not an advance in the state of the art. I'm not aware of any work on native application environment for Sawmill. If such work has been documented, I would really welcome a pointer to a paper or a technical note!
I do not *remember* discussion of application environment for Sawmill, but in those days Sawmill was pretty young. Perhaps things have gone further since then.
