I entirely agree that an accreditation along the lines of the way that CLECs are approved in the US makes a lot of sense. But I also have to agree with Bret that you will never, ever, get any agreement on "semantic harm". The IP crowd finds harm in any new domain since they see it as yet another place for squatters. You'll have to drain the IDN swamp and decide what to do about a domain that uses unicode characters that look exactly like COM, or maybe not exactly but pretty close like C0M. Is it a problem if two domains mean exactly the same thing like COM and BIZ? Approximately the same thing like AERO and TRAVEL? I don't know the answer to any of these questions and neither does anyone else. I put some notes in my blog on the STLD renewals noting that STLDs to date have all gotten only 5% of projected registrations, so they're all failures, so I don't see any point in doing more of them. But do we need more fully generic TLDs?
