Currently, most of the modules external to Python will either do a large
intensive database lookup, or a heavy esoteric calculation.  There will be
frequent calls to them, but based on what I just said you can see that the
percentage ratio of the time it takes to receive the request and then return
an answer to Python, versus the lengthy operation itself, will be quite
large.  (So pretty much any of the communication strategies I outlined won't
be signicant when it comes to the overhead of the call itself, regardless of
the protocol used.)  Yes I too really like the socket approach, although
setting up the data object transmission format, especially the quality
control and validation parts of it, and creating a robust async receipt
mechanism on the client side, is a headache.
