Not really I've been sitting on a gigabit connection for a few months. As far as mining it's not really needed. You can run nodes but again... you could do that at normal broadband.
I hope someone comes up with a good idea. I would love to make money off my extra bandwidth but it is not that easy. There was a torrent client that paid out for seeding that was in beta.... but I did not join as I did not think torrents people are paying for ... chances of it being legal vs illegal is slim they are sharing something opens source, etc. Other then that there has not been a lot.
I would love for someone to post some thing new if there is a new way to use fast connection's for bitcoin community or personal gain. But I think it's still pretty slim chance it's changed.
