Thanks for the clarifications, much appreciated. Looking closer, I realize `arrjson` is anyway separating out the values, which isn't what I'd want to ship a table from one service to another.
What's a good way to embed the table as a byte stream that can be "read back out" the other end? I see `arrio.Copy` being publicly callable, and a `TableReader` should serve as its reader, what would the `Writer` be in this case? The one in the `ipc` package ?
