MIT's iFind Service: Page 3 of 6

In contrast, iFind provides the location information using nothing more than the functions of Wi-Fi. It's possible to use the same algorithms that were used in the proprietary wireless voice systems to identify the location of a Wi-Fi endpoint, so locating people and objects over the Wi-Fi network is more feasible, without RFID tags.

YouTube and other social-networking services let friends socialize. We imagine iFind will be used similarly. Although it's intended to let students get together to work on school projects, it lets you find a friend for any reason.

The third aspect of iFind is its ability to facilitate collaboration. With iFind users can more easily decide how to meet based on the location of the group members.
