Well, my thought was a kind of on-the-fly LOD - for example - imagine a Quake-style FPS - in which you have certain objects that would look good close up with depth - such as a keyboard which from a distance (or not visible) is completely flat, yet as the player approaches it, you can subtly apply the depth by moving the vertices.
I'm talking in general here - not necessarily a keyboard - maybe a large control panel that has buttons on it that you want to just subtly make 3D, because the player may view it at an angle when close to it - the panel itself will already be in 3D, it is just cosmetic things that can 'shift' in and out of 3D. Of course, you could just apply the depth separatly with primatives (add little cubes in and expand them) - but I am sort of *feeling* my way into what you can use the Blitz3D vertex stuff for.
