I asked for the same request for any kind of object (especially empties).
The answer I had from Campbell was : "super easy to do, nobody has time to
do it" :)

that was a year ago, and I doubt the status changed :p

> Hi everyone,
> I'd like to request a feature added (or fixed?), which is colored point
> clouds. As-is, if I import a point cloud via PLY or some other format with
> vertex colors specified, they simply show as black. This is because vertex
> colors are only supported for faces. I had a hacked together script that
> takes a PLY and converts vertices to small tetrahedrons, and then vertex
> colors display properly. This is terrible for file size, memory, and speed
> reasons, plus the tetrahedrons don't display as "nicely" as pure verts do.
> So basically, I'd like Blender fixed or otherwise modified so that vertex
> colors display for verts not connected to faces. It would save me a fair
> amount of time and headache if this were patched sooner rather than later,
> and I know everyone is busy, so if someone could make the modification (and
> maybe make me a Windows build??) I'd be willing to pay for this. I'd be
> happy to assist in any way I can. I've done plenty of software development
> but never on Blender, and I'm occupied with other stuff at the moment.
> Here are some test files for anyone that wants to check out the current
> state:
> http://www.threespaceimaging.com/dl/shoe_part_verts_only.ply (5MB)
> http://www.threespaceimaging.com/dl/shoe_part_tetrahedrons.ply (27MB)
> When importing tetrahedrons, add a material to the object and check
> Shadeless as well as Vertex Color Paint. You should see whites, grays, and
> pink sections. You can do the same with the verts-only version and confirm
> that it does not work as expected.
> Thanks everyone - feel free to contact with any questions.
