I don't think one application/process's memory space will be made available to other applications/processes. It's fundamentally hard for processes to share their address spaces.
IIUC, with Arrow, when application A shares data with application B, the data is still duplicated in the memory spaces of A and B. It's just that data serialization/deserialization are much faster with Arrow (compared with Protobuf).
