Jeroen,

Do you think that a site would try to connect to the Internet with *just* ULA addresses? I would think that any responsible site operator would recognize that ULA addresses are not globally routable, and would give his global services PA or PI addresses as well. In IPv6 it's easy to assign multiple IPs or subnets, so if I were a site using ULA-C addresses and wanted to offer services to the entire Internet, I would allocate my servers IPs from each of my providers' PA blocks for global reachability, and perhaps keep ULA-C for address consistency with my internal systems and that of any private partners I share ULA-C routes with.
