Hey Gustavo,
I'm going to try your approach. Never manipulated uvs in ice before :)
Hey Leonard,
This is far beyond what I know :) Would use some already made compound
in that case :)
Thank you guys, this should keep me busy this afternoon, I'll let you know.

Ps, not all renders support Projection and Image Lookup nodes :(

Hi Olivier,
Leonards approach sounds very good and not much complicated...
Still I was intrigued to see if what you suggested was possible,
and it is if you do some magic in the render tree.
What you need to do is get closest location on the projection you
want to evaluate and store this values as a ICE attribute, like
UVoffset, for example. Then in the render tree get a image lookup
node, so you can roll your own texture projection, bring in the
ICE attribute you created, and the original UVs of your particles
(with Projeciton Lookup Node). Basically what you need to do then
is to rescale your projection so it matches the world size of your
particles, and add the pre-calculated offset. Hope it makes sense,
here are some images...
