Yes.  But would you grant me that this is done in a more orderly fashion?

I realized shortly after my post that calling external executables is the norm, not the exception.

Also, I must apologize, my general tone in that message was terrible.  I'm experimenting with quitting smoking.  Suggestion: never start.

No.  Well, kinda.

Yeah, I've thought about that a little bit.

I heard somebody say the other day that according to some survey, x percent of people don't know the difference between a search engine and a browser.  Would they know the difference between an application and a VM that auto-starts an application?  ...If you just change the title bar of Virtualbox to say "Emacs" instead...

I wrote ~2200 characters on this subject, just now, but then I stashed it away rather than present it here before asking: has this been proposed before? What was the outcome?
