Bump: Particles/VertexLit Blended?

Hi I know that Particles/VertexLit blended can have realtime lighting in it but if the light is behind the particle it looks dark because no light can shine on it...

in unity 3 in the tree-soft-occlusion-leaves shader it can except light from all angles...

is there anyway to edit the shader Particles/VertexLit blended so that it can except lighting from all angles also???

thanks!

Can't you just create a material with the particle "picture" in it, but give it the FX Glass?
