Just to clarify, you really can't get a vertex list from an ssgEntity,
some ssgEntities are not geometric objects at all.

The most obvious example of an ssgEntity that doesn't have a vertex
list is an ssgBranch - but I've been thinking of creating a node type
that uses OpenAL to do spatialised 3D audio in an SSG scene graph for
example.

First you have to have an ssgLeaf of some kind.  Norman's code
(above) checks that first - which is good.
