I must be missing something here.

What is the advantage of passing the open file rather than just the
fully qualified file name and having the other process open the
file itself?

I would tend to not go this route, but would opt for one "file owner"
process and use a message based protocol if heavy sharing is envisaged.
It feels "more right" to me than to have different processes read and write 
to the same thing.  I can imagine big Dragons with sharp teeth...
