Location aware computing is finally coming to North America. Cell phone companies have services where you can see on a map where your buddies are, or their phones are in the city! MIT is letting students see where their buddies are via wireless network connections, C|NEt reports.

"The software, called iFind, looks at first like any typical instant-messaging program. But iFind's buddy list is augmented by a map showing where on MIT's campus those buddies are in real time. The map plots buddies who are logged on to the MIT network via Wi-Fi, allowing users to create unique mini avatars for each friend. Users can see who is hanging out on the banks of the Charles River and who is one floor up from them in the library."

Now if only we could use RFID to know where the book we want is in the library...
