I would not use INI if the systems are writing data. While I've had
plenty of success reading INI files in parallel - I seem to recall that
the file is just streamed out without regard to which version is on
disk. I think the file is completely refreshed.
I recommend using a DBMS system of some sort for read/write ops in parallel.
