Collision detection for particle system/replicator?

Here's a question for all you motion heads, let's say I wanted a whole bunch of objects to be randomly moving around but never overlap or cross/pass through each other (i.e collision detection), is there any way this can be done using a replicator or particle emitter and behaviors in Motion 5?

Thanks,

btmk, the actual Motion5 offers collision dectection only for the 'box' you're looking in.

I don't know what 'btmk' means, but if you mean the "Edge Collision" behavior, that's what I thought.
Oh well, just thought I'd ask, in case I was missing something, or there was some kind of work around.

best to my knowledge
