This is pretty good stuff -- I work with WorldBuilder and we are currently looking into either making a plug in for our own product or adding specific functionality for architects and landscape architects.
Right now WorldBuilder is used by architects and landscape architects, but I think we want to create a streamlined workflow and some specialized features to make it easier for you guy (and gals).
What I might do is try to work with Jeff to create a small group of architects that can help us with making sure this is a good tool for architects. We can throw in some heavily discounted software as well.
If you think you might be interested, contact either or both Jeff Mottle and myself. Once we gauge the level of interest, we can figure out what, if anything, makes sense.
(By the way, WorldBuilder 3.5 will have true 3D clouds, to answer an earlier post)
