Today I noticed yet another python to MPI binding released, as announced on the Daily Python URL ( www.pythonware.com/daily ). It was created by an engineering school in Argentina. They do mention the other mpi projects in the preamble to the documentation, but curiously, they list pyMPI is not being interactive. Obviously the word curious is a bit of an understatement here, since the pyMPI docs rightly emphasize it's interactive abilities..
