The flash demo on that page is definitely worth a look! The good thing about this is that it's free, and it works with Bluetooth, which is pretty standard with most new phones these days. However, it seems more applicable to individuals who like meeting new people, as opposed to those who stay within their own contact list - that's the impression I got from the demo, anyway.

Something like Dodgeball seems to offer a fuller mobile social network experience, but if Nokia bundles a social networking app on their phones, then of course they will have the upper hand. The file sharing thing is also an exciting area, especially in terms of sharing MP3s and so forth. I wonder if this will really take off?
