no you're right here. maya is a good tool for that. what you're looking for can be done by maya.

it's actually not very complicated and just a thing of using goals and fields to the particles. a simple example here.

create a surface (a single nurbs plane here) and create an emitter (doesn't matter which kind). now select the surface, shift select the particles and in the particle menu hit "goal". now the standard settings are 0.5 means that the particles are half way attracted by the surface. in generall it's now just a thing of good keying the goal value. you can also add a field to the particles to get random motion.

this is not the end, because then goal is 1 the particles will stick to the same places where cv's are. so we have to create an expression to avoid this.

select the particles and look for "add dynamic attributes". hit the generall button , select the particle tab and select goalU and goalV, click ok. now in the folder above in the AE you'll find the new attributes. right click and select creation expression. type

goalU = rand(0,1);
goalV = rand(0,1);

the values 0 and 1 are the min max Values for the U and V coordinates on the surface.

hit create and that's it.

if goalweight is 0 the particles are not attracted by the surface and react on fields and their motion etc. if it's one only the surfaces attracts the particles.
