The RIRs are working to enable clean transfer of address space 
holdings, using X.509 certs. While one could do what what Harald 
suggested, the new address space holder would have to worry about HP 
revoking the cert it issued to effect the transfer. A "cleaner" model 
would call for HP to effect the transfer through a registry, so that 
HP is no longer in the cert path.
