Voice input does fairly well these days as long as you're working with a fairly constrained set of words (free form recognition still needs help). >I don't agree with this line of reasoning.

(I guess the words "OK" and >"Cancel" are good candidates for a VAI) In any case, I'll add that 3D >model previewing can be taxing on the renderer and can slow down the >entire dialog.

(Think about how you choose a model on 3DCafe.com - name and >thumbnail.) You definitely wouldn't want a 3D panel that shows only a single model. I was thinking more along the lines of a fisheye WIM containing many models. To ease the burden
