Unfortunately, CloudFlare requiring root authority for a domain is simply a non-starter for me (or $dayjob). However, I understand why they do it -- DoS protect

Unfortunately, CloudFlare requiring root authority for a domain is simply a non-starter for me (or $dayjob). However, I understand why they do it -- DoS protection and ease of maintenance on their side. I do wish they supported taking authority of a subdomain, or simply required a CNAME like many CDNs.
