Is there a way to animate the "Motion Path" Particular uses or blend it from from "Motion Path A" to "Motion Path B"?
Goal: Particular "liquid" traveling inside hose path as the hose path changes shape over time.
Or, put another way… I want to
1) move "liquid" spheres along a custom "hose" path shape, and then
2) change the shape of the hose path over time.
I've figured out step 1. I created a light and animated that along the custom path I'm using for the hose path shape layer. I then set the Motion Path (in Physics->Air) to be that light. I've got everything flowing nicely along the hose.
However, I can't seem to figure out step 2. Is there a way (with Particular) to animate the shape of the "Motion Path" reference in the Physics->Air section?
I could probably create a C4D solution for this but my client needs edibility within AE (CS6!).

Sorry it took me so long to respond, been a crazy week…
Thanks for your advice. Unfortunately that tutorial you recommended wasn't what I was after (though it was informative). I really needed to flow my liquid inside of a specific hose shape that morphed between "before" and "after".
In the end, I decided to precompose a long thin rectangle of particles going straight. Then I brute forced that rectangle into shape using Mesh Warp. Luckily, you didn't need to see that the particles were really "circular" (there were so many it was more of a continuous flow) so you could not tell how much I distorted things. This method worked for this shot.
Of course, I'd still love to be able to shoot particles along a specific path of my choosing and have that path change shape over time…
