I haven't actually been able to do this.  One issue I ran into with
PLY export is that the file format has a lot of semi-defined
standards, and I don't know precisely the "right" way to do them.

Looking at this message: http://www.blender.org/forum/viewtopic.php?t=12262

Suggests that a header format of this type *might* work:

ply
format ascii 1.0
element vertex 24
property float x
property float y
property float z
property uchar red
property uchar green
property uchar blue
element face 6
property list uchar int vertex_indices
end_header

But we use format binary.  Does that roughly line up with the header
of the exported .ply files you're working with, other than the vertex
count and the binary/ascii difference?
