Bob,

   One approach (to the technical aspect) would be to do it in two phases.  The 
first phase being somewhat of a hack to simply warp a layer to appear to be in 
perspective.  The second phase would be full support of 3d perspective rendering 
and 3d objects (terrain, buildings, etc).

   For the first phase, add a value of "2.5d" to the LAYER's TRANSFORM object. 
When the layer is rendered apply a simple warp to approximate a perspective 
transformation, and copy the result into output image (or warp the features as 
they are written into the output image).

   For the second phase, get lots of funding :)
