Dan- I haven't been really involved in hang gliding since 2002 or so, but as far as I KNOW, "Licensing" of hang glider and paraglider pilots is still not within the purview of the FAA. In the US, pilot rating and instruction is administered by the US Hang Gliding and Paragliding Association (USHGPA), headquartered in Colorado Springs, CO.

Many flying sites and commercial operations for foot launch, ground tow (winch) or aerotow require liability insurance. This insurance is available to the pilot, site owner or commercial operator through the USHGPA. It is an included benefit of USHGPA membership, or a purchased certificate of endorsement for the particular site, club, landowner, commercial operator or government entity that has influence or financial interest in the particular site or operation.

In order to fly at one of these insured sites, USHGPA membership (or reciprocal foreign organization), and applicable pilot ratings must be presented.
