There is something very smart going on here, but it's not the idea of using DNS to store contact information. What's smart is the ability of Telnic and its affiliated registrars to convince everyone (ICANN, NYT, probably most HN readers) that they're trying to do something vaguely cool but naive, when in fact they're just going to cash in a huge gift from the internet.
Here's the secret: new top-level domains are virtually guaranteed to make tons of money for registrars. Every medium-sized to large company is going to buy a domain in a new TLD; it's worth the cost just to avoid having to deal with a squatter later, even if it is (gasp) $400. If you can convince ICANN that you have good intentions, or that you need a country code even though you're part of the United States cough.prcough you are going to get a lot of easy money over many years.
And yet, we'll still look back at this in a few years and say "yeah, those .tel guys must be really pissed that nobody adopted their cute little standard."
This is incredibly stupid. I can add any record I like to my DNS. If things start querying DNS for those records, fine. But... what is .tel bringing to the party? My DNS server which happens to be at a .org can serve any records it likes!
As CompanyX, why would I want to buy companyx.tel, instead of just sticking those records on my existing companyx.com?
Individuals can also choose to display their location, allowing their contacts to see where they are at any given time and opening the door for location-based services.
As far as I know DNS takes up to 24 hours to update all nameservers, rendering this service completely useless.
Sort of. Depending on where this is actually stored it can be instantaneous -- at work we have a pair of servers that serve DNS via MySQL replication, and time from putting data into the master and seeing it in DNS is well under one second.
If they're suggesting you update the .tel TLD servers with your information, the sky's the proverbial limit, but it would be possible for them to keep it pretty tight.
The real problem with this is that there's no notion of ACLs or multiple viewports in DNS -- I reeeeeeeeeeeeeeally don't want any spammer who can find me@iigs.tel to be able to spam me with data from GPS me.iigs.tel records.
You can set the TTL (time to live) of a zone to whatever value you like including zero to force every lookup to go to the authoritative servers (do not do this, it will make your site slow for users and your network administrators grouchy). Most dynamic dns providers have a default of 60 seconds.
From the article it's hard to tell exactly what they are talking about, but it sounds like any of a number of schemes for abusing DNS as a federated database.
Now I could be wrong on this, but I believe that's at the EXTREME end of things, I would say with the way DNS is updated now it usually takes under an hour at most. At least that's my personal experience.
From the vids I saw, the main benefits of getting a .Tel domain is so people can easily retrieve your contact by going to your .Tel site either on their PC or mobile device. This information, in turn, can easily be updated by some kind of admin panel by the user, which in turn is updated by anyone else retrieving the info.
Couldn't this same thing be achieved with a simple script and a database? I fail to see the utility of going to a .Tel domain rather than company.com/info or something else. Is it just to bypass the need for hosting?
I think this is a good idea if it takes off. Being able to add billgates.tel to your various e-mail accounts and having your e-mail programs update your contacts daily and before you send an e-mail to that person would be incredibly helpful.
I just got my first smart phone yesterday and am having trouble trying to think of the best place to keep a 'master' copy of my contact records. This could easily solve that problem.
Great idea but DNS is not exactly the most secure of protocols. Also, the current domains can already do this through arbitrary records (as has been mentioned already).

How naive indeed.
