The concept behind Barrelfish
As OS design seems to have been understood in some blogs that are just as multicore or SMP system.
The concept behind the other Barrelfish distributed systems coming from Microsoft Research is an interesting technology news: a multikernel able to communicate with user space and with x86 processors, ARM, CELL or graphics chips and all constitute a single system eyes of those who operate it.
Then this system in a primitive state seeks unprecedented modularity in distributed: it is not an implementation advantage quadcores resources, it is spread in heterogeneous clusters or configuration NUMA (non-parallelizable) by intercom protocols URPC of a group of nuclei coupled in one general system.
Is being planned under a BSD license (open but sealable).
The only source that explains in detail ( in English )

Does anyone remember the decentralized modular system try without kernel and 100% rechargeable without restarts and never moved from theory? Unununium called and returned (assembler and BSD license). Though still but slightly profiled are the initial self-replicating systems (see the monolith that goes "hyper" when you get Linux 2019).
