@SSwift, I saw your code used a timeelapsed parm but what made you use this rather than a speedfactor parm defaulting to 1.0?
<edit> I think the problem is I'm trying to leave too open a question. If I write a Particle System (for example) and give it to somebody else what would be the best method so they can plugin their own 'timer' code?
