Well, I think they can score about 1 1/2 out of three. They can carry passengers and are certainly reasonably aerobatic (positive g only!). There's a good bit of video circulating of a chap looping one of these (actually a paraglider, I think), in fact doing several "loops" one after the other at a high rate.
Air law is a part of the club pilot training syllabus, but was the chap at 100ft actually breaking the 500ft rule? As I recall, it's 500ft from any object, not 500ft above the ground. If he was over open ground and more than 500ft from the road, he could have been legal, I think.
