Re: How paf is implementing URNs and URCs today

Mine and Patrik's implementations are very similar so (without checking
with him) I'm going to ditto his implementation as what I'm also 
working on. My additions include a new DNS RR for facilitating
the DNS lookup (and for replicating authority servers) as well
as implementing the MODE command for whois++ that will
facilitate semantic gateways between protocols/syntaxes....

Life is a game. Someone wins and someone loses. Get used to it.
