The puzzle is how would you apply the RGP to situations where the domain name was required to be deleted in accordance with the 15 day rule for whois data rectification? To focus your thinking, just WHAT whois data would you "restore" to the domain name? The original inaccurate data? Or would you "restore" the domain name to some other contact data simply because someone showed up and said, "Oh, gee, yeah, I moved, got married and changed my last name, phone number and email address, but it *really* was my domain name". If you implement the RGP that way, then you can kiss WLS goodbye, because every liar on the internet is going to show up trying to "redeem" domain names that were never theirs in the first place.
If that is still not clear, then consider one of Mr. Touton's examples. Someone complains about a domain name registered to "Toto" who resides in "Oz". Fifteen days goes by and the domain name, rather than being deleted forthwith, is put into the 30 day RGP queue. Now, if a house falls out of the sky, lands on Esther Dyson, and some girl with a dog takes her ruby slippers, is that going to be sufficient evidence to have a registrar pull the domain name out of the queue? If not, then how WOULD someone use the RGP to save that name?
If I only had a brain, maybe I would know.
