  >Mungi</A> is the *(OS) project that originally proposed a one global distributed shared memory, _(aka) a <em>single address space</em> or <em>_(SAS)</em> (starting with 64-bit virtual address space).

They are trying to build Mungi as a very pure _(SAS)_(OS), that is all data (even the systems') is in the single address space, and no other _(IPC) mechanisms are supported by the _(OS).
