Is it possible to call a function in the running editor assembly from the command-line?

It's possible to start the Unity editor from the command-line and pass the name of a static function to be executed. This is almost exclusively used to trigger an automated build process.

Is it also possible to call such a function from outside of Unity while the editor is already running with its GUI open? Basically, I'd be interested in writing a .bat-file that, when double-clicked runs a function in the running editor instance. My command-line script would be its own process, so I doubt that it has the necessary rights to do so, even if it was possible, but just asking in case there is some hidden feature or workaround, I don't know about. I was almost thinking about placing some sort of marker file in the project, that when changed, would trigger a custom import, which could then call my function, however, I then realized, that some users (myself included), don't have auto-refresh enabled and so I couldn't ensure that it actually gets run.

 

Having written a few programs I've only ever seen parameters getting passed at the start of a program. I don't know if Unity has anything like what you ask for, but an alternate solution could be having unity create and listen on some network socket?
