Nope - convex polygons only. Any concave bits will be filled in.

I had exactly this problem a few weeks ago and had to connect fake
wireframes out of ribbons as you describe. It's time consuming though -
I made a script to display the vertex indices of a polygon object to
make it easier. I'll try and publish some of this as soon as I can.

The other alternative is some sort of shader, colour dependant on the
continuity of the surface so the corners change colour or something more
or less like that. It probably won't look as good.

cheers,
