I have been always dreaming of a system that you can travel around with, and talk to other people around you who are using the same system. Something like an instant messanger, but wireless. In fact, the best way to describe it was a combination of an instant messaging software and a mobile phone.

Now, the dream has come true: Trepia is your instant Wi-Fi community (found it through Wi-Fi Networking News). It's a revolutionary networking application that lets you instantly meet other Wi-Fi users in your vicinity. Other people will simply appear on your contact list, allowing you to communicate with them.

So, if you have a wi-fi card, simply download the program and start exploring your area! If you don't, you can start looking into buying one. You may buy a card for $40 and the base station is sold less than $200.

Next dream: Online video chatting in the neighborhood! Happy Trepiaing!
