I've been trying to tackle precisely that problem.
Would someone please help me out and point me at a way of efficiently exposing a read-only block of memory to Python?
EDIT: Looks like "MemoryView" introduced in 2.7 is the answer.

as for shared memory, have you tried just mmap'ing the node from /dev/shm ?
EDIT: I just saw your edit. That's what I'm doing --- shm_open(), ftruncate(), then mmap(). A little annoying that it doesn't automatically kill the shared memory when the program terminates, but still...
