Sorry, but Namecoin is a scamcoin! DNS works on low-end computers, Namecoin is an overkill requiring vast storage and constant syncing - you can recall what happened a month ago when Coinbase went out of sync with the blockchain and were pretty much offline of hours. Using the blockchain for absolutely everything is an abuse! DNSSEC + DNSCrypt are pretty fine for me! Plus, being a scamcoin makes .bit domains pretty expensive - right now it's $14/yeah - way more than a way more useful .com!
