As far as my experience goes, there is no obligation for a plugin to return, especially if it invoked without any indication of a specific image (ie, no image as argument). So you can launch a plugin from Gimp that will wait in the background (it is another process, after all). But my plugin that does this doesn't issue any commands against existing images (so can't tell what happens in this case), and you would also have to identify the images.
