I'd prefer the OPoC proposal

[Markus Hanauska <hanauska@xxxxxxxxxxx>]

In all the domains I have registered, all contact data infos are the  
same, they are all my address data. I see no point in this  
separation. The whole point of WHOIS was to have a contact address if  
either there is something wrong with domain or there is a technical  
issue that needs to be resolved. This was not about ownership,  
trademarks , buying domains, knowing who pays for it or any other  
marketing aspects, it was only to have an admin contact. And that is  
just one contact. For all other issues (including law enforcement and  
the like) it is easy to contact the service someone used to register  
the domain and they will have the address data (as they need to send  
bills for their service to their customer). So the OPoC sounds most  
reasonably to me. Just my 2 cent.
