[Sidefx-houdini-list] VOPSOP by ID

I'm working on a method to re-time aka interpolate particles. I would 
like to use a vopsop and do this as a post process. The idea is to use 
the point position of the neighboring frames and their velocities to 
calculate an in-between position.

The problem is, a vopsop works by point numbers and not particles ID's 
and since point-numbers change when a particle dies...

Any suggestions? I was thinking about the sort SOP, or something like 
that. A method to match the point number by the particle ID. Still this 
would result in missing point-numbers and I'm not sure if Houdini would 
like that.
