No, it doesn't seem to be that. I'm often in company with people with the same software, but when you're close enough to have bluetooth working it seems to always be much simpler to collaborate through traditional means (even using the proverbial pen+napkin). Well, except for interchanging contact info, as already mentioned.

It's a bit vague, but there's probably some stuff in there that could actually work. Not sure which though, which I think is what I'm getting at.. a lot of things that _seem_ to be very useful turn out not to be, and sometimes the other way around.
