Running .obj with blenderplayer


I was reading about the bender player method of making an exe for blender at wikibooks.

Well, I was wondering if blenderplayer.exe could run files other than .blend with a python plug in. For example, if I exported a file in blender as .obj with a python plugin, could I in some way get blenderplayer.exe to read the plugin to run the obj?

Sorry if it doesn’t make much sense. I wasn’t really sure how to say it.
