Besides the forestry thing, a slightly modified version of this machine would be extremely useful doing cleanup after hurricanes. My hometown got pretty well flattened by Ivan this past summer, and walkers like this could've easily gotten into places wheeled or tracked vehicles simply couldn't reach. Between city/county contracts, and the utilities having to clear all the debris to get their services back up and working, an enterprising company could've paid for a fleet of these things had they had them in position to clean up after that one storm.
