Hi,

I guess that nearly no registry has implemented the transfers of contacts. The 
benefit is neglectible and introduces some unwanted side effects. As Seth says, 
especially, automatically transferring contacts along with the domain is a 
really bad idea, as these contacts may still be linked with other domains of the 
losing registrar.

Automatic copying of contacts could be done, but this increases the garbage -- 
without copying, a registrar can theoretically reuse an existing contact for the 
very same person he has created earlier. Host objects cannot be copied, as the 
host's name is the (unique) key to the EPP object (contrary to the ID of the 
contact, which is not part of the content) and therefore no two hosts with the 
name may exist at the same time.

Another registry implementation approach is to use separate object/ID spaces for 
each registrar. A registrar cannot see/access any object of another registrar at 
all. In this case, copying is mandatory, or a new set of contacts must be 
already provided when the domain transfer is initiated (not possible in EPP 
without extensions).

Regards,

Klaus
