Not really at all. They're going to have to add a whole load of features and new UI elements which will increase the cost of updating and progressing the browser. Either it's going to be a half assed Skype tacked in behind a menu somewhere, or a browser cluttered with all the visual UI of a chat program. To say they had to do most of it anyway is compete nonsense. The protocol is like 1/10th of a decent chat program.
