Yes there are other ways and I suggest that the optimal choice of protocol for publishing this information is LDAP, not DNS. ... Next step is to get ISPs to replace their creaking antiquated rwhois servers with LDAP servers.
Technically, this is reasonable, and I suggest that everybody who shares this view do some actual work in the IETF working group which is precisely devoted to the subject : Crisp <URL:http://www.ietf.org/html.charters/crisp-charter.html>. LDAP is one of the two actual proposals discussed at Crisp, the new IRIS protocol being the other. Do note that Crisp explicitely works also on address registries, not just domain registries.
I am suggesting that the starting point here is to get ARIN to set up an LDAP server to authoritatively identify the leaseholder for all IP address space.
I suggested the same to the RIPE-NCC some time ago. No real interest. I believe that the RIRs have enough work :-} They do not seem to participate in Crisp either :-(
