S60 Open to new features

I was in Vienna this weekend, riding public transportation, and observed something that I haven’t seen yet in Helsinki…young kids are listening to music from their mobile devices and they are sharing the experience with their friends. Here’s the problem for me: they are listening to it in public spaces and I don’t necessarily want to listen to their music--especially if it’s competing with others talking on their mobiles or listening to their music (even with earphones, you can still hear “something”).

I know this problem is elsewhere in other European cities, e.g. London, and there have been public responses to this (and, in turn, some new rules that “prohibit” these behaviors). But it forced me to think about this: there are users who would like to share their music with their friends; they want to do this anywhere, anytime and, most likely, with no restrictions. My guess is that this doesn’t stop with music--users will want to share anything and everything (e.g. pictures, MMSs, video clips etc). So, the bottom line is that there is an obvious need yet to be met…how can/will/have developers respond(ed) to this need?
