MWC was quite the eye-opener, but it's hard to say how much traction it'll gain in a world already inundated with short-range transfer protocols. Bluetooth, Infrared, Wi-Fi Direct... the list goes on and on (and on). Essentially, AllJoyn is an open-source software system that doesn't actually have to run atop Qualcomm hardware; if implemented in a particular app, it can enable peer-to-peer sharing with others based on location. If you're standing near someone who also has an AllJoyn-enabled application, you two (or more) can interact -- if you're both using Bluetooth, the range will be around 30 feet, but if you're both using Wi-Fi, it'll obviously be greater. Qualcomm's hoping to entwine its homegrown FlashLinq (more on that in a separate article) in order to let people use this while being up to 1km away from one another.
