The Muen Separation Kernel is the world's first Open Source microkernel that has been formally proven to contain no runtime errors at the source code level. It is developed in Switzerland by the Institute for Internet Technologies and Applications (ITA) at the University of Applied Sciences Rapperswil (HSR). Muen was designed specifically to meet the challenging requirements of high-assurance systems on the Intel x86/64 platform. To ensure Muen is suitable for highly critical systems and advanced national security platforms, HSR closely cooperates with the high-security specialist secunet Security Networks AG in Germany.

The webpage contains instructions for building the kernel yourself, for installing it in a virtual machine, and for running it on real hardware.

Fair enough. I guess my point is that IPC means "Inter-Process Communication" - if you use it inside the same process address space it becomes a glorified function call. That's fine from an organizational perspective and does yield you modularity, but it isn't really IPC anymore because there is no longer any process isolation.

I do not see why IPC and process isolation must stick together. Even within the same address space (aka process) using message passing serves to get a better design (and even w/o the overhead of copying data).
