Bobby,
multireplication (preferally along a path) uses one object. You'd have to combine the objects to get them all used at one time or make several paths - either way it would be ordered not random. 

(If you're refering to something in the terrain editor which I seem to have some dim recollection of, that wasn't what I was talking about. I am sure BT (amongst others) would know about using the terrain editor in that way if it can be done.(or as I recall, Agent Smith; if he could be found.)

I can, however, show you how to make a path using the animation feature in Bryce if you'd like, or refer you to Peter Sharpe's tuts on the subject of multi-replication (i.e. making shells etc.)

sorry not to be of too much help here,
-TJ
