I've made minor use of glisses on some videos, like on the song "Crazy" (briefly in the last verse, and Yakety Sax (octave gliss into the main theme). And I've done some minor glissing over half/whole steps in pop and sometimes in classical music (violinists do this, right?).
I suspect longer glisses will be called for in modern compositions at some point, so I put together a quick instructional video. On the end are a few examples of glisses from me and from trumpet players.
