You can contact me now, and apparently for the next 50 years (based on the assumption that the service, the world, and I will all be there), at the universal handle =David.Orban, which is my i-name. (A recently introduced global system by Identity Commons, and the 2idi, an i-broker, based on open data sharing standards respectful of privacy.)
I-names aim to represent a contact point by all means, email, phone, fax, etc. , and to enable location management, single sign-on to websites, trusted social networking, and more.
I know the first thing I want from it: to become the foundation of portable , transparent, and open reputation systems.
