I was also thinking of this when I read "data in a shared memory" (besides approaches like http://www.kerrighed.org/wiki/index.php/Main_Page). Wasn't this also one idea behind "High Performance Fortran" - running in parallel across nodes even without knowing that it's across nodes at all while programming and access all data like it's being local.
