I love to see threads like this. It empowers more people to try things. When they can visualize what is done, they are more likely to try something themselves even if on a smaller scale.
In every project it is only as hard as the hardest task. The difficulty is keeping perspective of the task.
I find that most people can do even some of the most difficult task; they just don't know it. "Will" and "interest" are of the most important required skills.
I find if I beet my head against the project long enough there is little one cannot do; but only if the will to do so exist.
