This is exciting for us too. Our engine uses some small parts of Qt, but we'd intentionally kept the usage somewhat limited in case we ever wanted to factor it out so that we could deliver our stuff in some form other than as a web service. It's nice having that out of the way. I'd also had a chance to chat with some of the Trolls before the news broke since my initial reaction was, "What does this say about Nokia's future commitment to Qt?" I'd guessed that Nokia would do free-as-in-beer licensing, but not free-as-in-our-competitors-can-fork-it licensing. Turns out that there are some reasonably sane business reasons for the switch. It'll be interesting to see how Nokia plays their cards in the just heating up mobile platform wars and how Qt factors into that.
