Hi Rob,
You can use a vector state node with intersection point, but this only gives you world space co-ordinates. I'd need to implement something to provide individual co-ordinates per particle for textures.
Cheers,
Alan.

im sorry phil, which website? Alan's website, here
http://binaryiris.com/main/?id=GenieTail or another one?
the genietail page has no examples or instructions on how to get texture
UV info into the particle volume all it says is this:-
'colorDensity: This alters the density of the cloud - multiplying each
step by it's value. It is sampled at each point so can be used to add
texture within the volume of the cloud.'
if i plug an overall green image into the color density input of the
shader, the color density *does* go greenish, but if I plug a
multicolored image into the color density I get some kind of average of
all the pixels colors. I would like to know where is the pixel xy info
applied in relation to the volume of the cloud? can I apply UV's or use
Cloud local space? I'd like some way of applying a new texture that
covers the whole of the cloud to vary the density.
cheers
