Address book as mobile Web's digital identity

OK, I have an idea. Unifying data behind your address/phone book name or nick name as a mobile URI and registered as an internet service.

People are in need to connect on the internet when on the go. Mobile phones do have these days more access to the Web.
But if they don't '''surf'' web pages ( limited usability ) they look for specific information , but one of the more compeling reasons to do this would be to search for information about people they know or might know ( socializing )

What if we think about address book in your mobile phone as your unique mobile URI ( uniform resource identifier ).

Could you as a mobile subscriber register ( to your operator or to some third party ) your address book name or nick name so that every mobile phone can search ( via phone's phone book ) and access your digital presence ( digital stuff ) which could be stored in a ''digital box'' ( as a type of mobile hosting service ) somewhere on the server ?

Your mobile pocket filled with stuff like Facebook or MySpace profile homepage .
Zipiko is an interesting model for connecting and communicating with others, and mobile URI would be of great help to those type of services.
Yes, do most people know where's browser on the phone at all ?
What if one of those ''internet browsers'' is in your phone book ?

Now, think about your phone as a tool for exchange . You can use your address book for this as well. Just send your photos or movies to someone from your A-book.
Yes, operators, bandwith and updating data from mobile phone is an issue , but looks interesting to me.

I am sure somebody already thought about this paradigm. Maybe Nokia's Ovi portal could be doing something with such an idea. Remember Nokia's Mobile Web Server project, but a bit different model.

Look how japanese used phone book in 2007.

Poll: Other than address book information, what sort of data have you exchanged with other people? (Sample size=mobile phone address book users, multiple answer)

Own phone number, mail address 44.1%
Photos and movies 35.0%
Downloaded pictures 8.0%
Deco mail animated emoticon 7.5%
Music data 6.9%
Schedule data 2.0%
Games 1.6%
Work-related data 1.1%
Other 0.9%
Nothing in particular 39.9%
No answer 0.5%

Even though I was in a camp for .mobi domain introduction, I wish to see this type of mobile URI funcionality implemented in the future.
