Using vertex colors is nice because 

a) blender already supports vertex colors, it doesn't support multiple textures
b) doesn't require extra features or performance of the graphics card
[I have to deal with computers that can't multi textrure]

so, essentially this is a novel way of using a radiosity calc [as
before], but having good results on a lowpoly mesh much more easily
