Depends if you need to have access to the object itself or merely look
up values in it. If it's the latter you could start a thread in first.py
that offers dictionary lookups via a specific UDP socket. Any number of
subsequent progs and processes could then pitch up and lookup whatever
values they like whenever they like. ~10 lines of code in first.py,
maybe 5 in second.py
