TCP/IP is also available if you are more comforatable with that.

VI Server is also using TCP/IP to communicate with out of process remote instances.
But of course it hides quite a bit of the complexity of packing data together that you would have if you do your own TCP/IP protocol.
Shared memory while indeed a possibilty under Windows (and Linux with a very different API)is indeed a bit painful to use since you have to interface the system API for that, and access to the shared memory is a bit painful too from within LabVIEW. It is likely the most performant version of interprocess communication though.
