:: Just saw this now  some easier way to track comments would be nice. Anyway I'm not sure the two are as separate as you note, the term "superscalar" generally means "runs more than one instruction at once". I think the i860 certainly fits this definition. Of the two, VLIW is more restrictive, such that all VLIW processors are superscalar (or what's the point?!) while only a very few superscalar designs are VLIW.
