  A few years ago, while I still lived in Britain, I signed up to a service tht gave me a 'portable' number. The idea was I could hand out this number to everone to call, but when they dialled, it put them through to me wherever I was, or at whatever landline/mobile number I designated.
  
  At the time the mobile industry was a little hectic, so people were swapping numbers regularly .. I think thi was just before cell phne numbers became easily portable. I moved house a couple of times around then too, and all I had to do when my number changed was go edit my designated number on the service web site.
  
  I'm not telling you this because I think the service was particularly good, or because I miss it. I think it was necessary at the time, but these days it i less so. If nothing else, people can always get me on my personal email addres, so I really don't care if they have an up to date phone number for me. But I like the idea of an emal address and/or phone number that we can carry with us for life. Sure there's reasons why some of us find we want or need to change contact details, but most people are lucky enough not to need to do that :-)

  If you really think that you own your domain name, I suggest you read Sex.com - http://www.amazon.co.uk/Sex-Com-Kieren-McCarthy...
  
  Basically, your registrar and hosting provider can give you as much grief over a domain name as your telco could over a number.

  This is precisely why I'm not a huge fan of phone numbers to begin with. It's just another way to contact me. Currently, including IM, email, phone numbers, and social networks, there are likely 30+ different ways you could contact me. This is wasteful, but worse is that when you want to contact me, YOU have to choose between these different methods. It's terrible.
  
  What we need more is a system that aggregates the different ways you can contact a person, so that if you wanted to talk to me, you wouldn't have to choose between email, IM, or a phone call. You would simple tell your device (be it computer, home phone, cellphone, etc) that you needed to talk to me, and bam.

  The premise behind this isn't actually sound. Phone numbers and domain names are what's known as a controlled namespace; in other words
  they are controlled by centralised and delegated authorities. So for phone numbers they are actually assigned by the ITU (?)
  at a country level and then local telco's receive delegated authority to assign the numbers therein.
  
  Domain names are EXACTLY the same. The top level domains are controlled, as are the region specific ones.
  
  In both cases you actually LEASE the number or domain from the delegated authority and therefore as with any controlled namespace there is
  little or no possibility or probability of ever actually "owning' the number. This "centralised" control is what ensures uniqueness.
  
  /* Gets a little geeky beyond here so bail out now if you want */
  
  The true problem with telephone numbers is not is the ownership rather the fact that traditionally the number has been tied to the service
  provider directly. So if you obtained a telephone number from one Telco, as it had delegated authority for that chunk of numbers you couldn't
  move it to another Telco. This was in part I suspect because telephone numbers are regionalised such that the average human is capable of
  remembering the numbers.
  
  Number portability seeks to resolve the changing of service providers, however is only possible within geographical boundaries say the same
  exchange - remember the heritage of circuit switching here.
  
  What is more useful in the modern and connected world is actually a controlled namespace that is NOT geographically constrained. One where
  you can be assigned an non-reassignable number (one that never changes and is always yours) which you can attach to whatever service you
  desire. Now IPv6 gives us a namespac big enough to handle this scenario but have you ever tried to remember an IPv6 number? Most people
  couldn't. This is where an abstracted identifier technology comes into play.
  
  With an abstracted identifier, such as iNames (based on the XRI standard from Oasis) you are able to create and link a human readable
  identifier (mine's =barney.craggs) to an underlying non-reassignable iNumber (directly mappable to an IPv6 address). This has a number of very
  cool advantages not least being the ability to have a single number if desired but also the ability to assign different iNames to the same
  iNumber for different purposes. So for example I could give business one iName and my friends a different iName both of which can resolve to the
  same iNumber (if I want) or be routed to multiple destinations.
  
  The possibilities are immense and I have over-simplified the technology for this comment, but in essence;
  - controlled namespaces are good as long as you acknowledge their limitations,
  - geographically constrained identifiers are limiting especially when the geography is actually directly tied to a service provider,
  - the use of combined re-assignable and non-assignable identifiers opens up a world of possibilities and a powerful driver for consumer
  choice.
