Is this possible under XSI's current particle system? Whats the best approach?
Yes. I don't know what the best approach is, because we don't know what specific kind of motion you are after, but I use a second order approach, that is one particle cloud to map out desired motion, and a second particle cloud using the points of the first as a goal. Here are the rules for this setup:
-Create your first cloud at a point density adequate enough to express your desired volume
-Run a sim on the first cloud if you like, or freeze it and use standard XSI deformations such as enveloping, lattices, or deform by curve
-Make sure that you are not creating or killing particles on the first cloud when the second cloud begins its emission. You need all of the primary particles to exist as the secondary ones assign themselves to goal points
-On the secondary cloud, use goal weights, dampening, viscosity, noise, and inter-particle avoidance to control the particle glue to the first cloud
