I'm still not sure I know what phenomenon you're referring to and am waiting to see if you'll provide any examples as John Hudson requested. If I knew what you meant, I (or John) might be able to comment on whether technologies like OpenType or GX (now reborn as Apple Advance Typography and very much alive though not yet well supported by apps).

BTW, Gerald made a reference to Adobe's Multiple Master technology: that's something quite different from OpenType and GX (AAT).
