I'm not sure I understand the problem: you can just create two pair of pipes using os.pipe(). If that's too low-level, you can wrap the fds using BufferedRWPair: http://docs.python.org/3.3/library/io.html#io.BufferedRWPair (actual incantation would be: r1, w1 = os.pipe() r2, w2 = os.pipe() end1 = io.BufferedRWPair(io.FileIO(r1, 'r'), io.FileIO(w2, 'w')) end2 = io.BufferedRWPair(io.FileIO(r2, 'r'), io.FileIO(w1, 'w')) end1.write(b"foo") end1.flush() end2.read(3) # -> return b"foo" ) An alternative is to use multiprocessing.Pipe(): http://docs.python.org/3.3/library/multiprocessing.html#multiprocessing.Pipe In any case, Python doesn't lack facilities for doing what you want.
