Just saw this new little script you might enjoy. It is commercial but looks useful.

And of course the more adventurous of you should look into one of my favorite tools for even more craziness: http://www.kilad.net
Nice find, I'll definable experiment with that script. $25 isn't too bad seeing the results it can produce. I'm not sure if I'd use that for brush geometry or just convert it into a model. It'd definable add more uniqueness for randomly placed buildings. Maybe even useful for sky box buildings. :)
