Yeah, website integration is definitely a planned feature. I've already discussed it some with noodle and tryout.
What I'd like to see is a site that I can feed data to (probably via XML or an HTTP request) and then it could display all the relevant information: tourney properties, registered users, the brackets, results etc.)
It would take a colaborative effort of various people, but it would really be neat. There
are things that need to be done before that, though.
