For the people who now understand the concept of .tel domains being able to store contact information, a tad bit of skepticism comes to mind when it comes to privacy. There's just so many opportunitists out there waiting to pounce on other people's private information. Spammers use email addresses for their trade. Scammers use other's data to trick people.

Telnic Communications Director Justin Hayward, however, dispproves all speculations by pronouncing that the .tel system is completely private and would not be infiltrated by unathorized persons. The .tel domain owners will have the power to publish only the contact information they wish to be made public over the web and keep "more personal information" known only to those they authorize like friends, family, business contacts and customers. Users can protection their data using 1028-bit encryption and mask their details to casual users while allowing friends and family full access.

Although there is no fool-proof system in the world, I firmly believe that Telnic's system after several years of development for the .tel domains will be reliable enough and with careful testing should be a very useful domain to have. The .tel domains usefulness far outweigh the negatives.
