Your question doesn't have a clearcut answer, because "appropriate"
depends on how you want to weigh different factors and what _your_
particular skill and experience is.

My suggestion:

Start by inventing your own protocol which does a _subset_ of what you
ultimately want, and then runn that protocol over stdin/stdout via the
'port' mechanism.

"C Nodes" and linked-in drivers ("C driver") come under the general
heading of "complicated and trouble-prone".

An observation: I don't understand why you want "middleware". That
suggests you're either over- or under-specifying the problem.
