When you start such an Emacs process as a subprocess, it saves you from having to setup a separate communication channel, which requires agreeing on a channel "name", making sure that name is not already in use, and can require extra care to avoid security problems. IOW, I think using stdin/stdout this way is many cases would be The Right Way and using a separate network/socket/namedpipe would be a workaround. > We could introduce such a feature for the batch mode, but it would > mean serious complications, and I just don't see the justification > for that. I'm not volunteering to do the job, admittedly. Maybe the easiest way to solve this would be to provide a function `make-stdin-process` which returns a process-object associated to stdin/stdout (instead of trying to change `read-from-minibuffer`).
