When I take my GSM-phone to Hong Kong (or to Stockholm) my grandmother is still able to give me a call while I am there on the same number as when I am at home... Address portability at work...
Not really, your phone doesn't have a routable number as such. It has a name which happens to be a number; and it can be reached outside its natural habitat after 30-90 seconds of searching, probing, and call setup. The Internet already handles name portability, even much better than the phone system. And there's no end to what could be done if dial-up users were charged two dollars per minute for out-of-habitat traffic, whether voice or 9.6kbit data. -- ------ ___ --- Per G.
