Though there's no official announcement yet, Opera has added support for BitTorrent to their web browser. I was just wishing for this yesterday. A BitTorrent download should be just as user friendly as a normal HTTP download. Moves like this will bring BitTorrent to the non-geek masses (users may not even know they're using BitTorrent). When it comes to performance, a unified application can manage bandwidth better than two separate applications; the browser could prioritize tasks differently and achieve maximum BitTorrent download/upload speeds without slowing down normal web browsing. FireFox and IE plug-ins (or preferably native support) must follow soon for BitTorrent to beat out Microsoft Avalanche in the long run.
