Chase, You can certainly do this. Define a set of regions and appropriate z-order. Regions can be defined anywhere within your root layout definition, and z-ordering begins with layer "0" (the bottom layer) and subsequent layers are on top of the previous ones. There is no requirement that you use all the regions you define, so throughout your presentation, choose the set of regions that give the experience you wish, and target specific URLs in the body of your SMIL presentation to the appropriate regions. The G2 RealPlayer from RealNetworks implements this. -Pat Boyle, RealNetworks Chase D.
