Hmm, good question. Each mesh2 hair is uv-mapped by meshmaker when 
created, and the pigment is uv-mapped on the mesh2... so, that seems to 
be happening indeed. I shall come back about this later as I do not have 
the code at hand at the moment. What I can say though: meshmaker is your 
friend! Last year, I used it for converting parametric grass blades (Uwe 
Gleiss: Lawnmaker) to mesh2 blades.

Waaah! [throws machine in the dustbin]

I know. Not so long ago, I also had to manage with two cores, and there 
was a time with only one... We are spoiled. ;-)
