Auto refreshing with jQuery

Guys I've been searching for a while and all I got is this guy tried to imply this feauture to punBB. It's like 6 years old, buggy and completely outdated, unfortunately. Is there any "modern" way to do that? I want a live forum, topics or forums must refresh automatically, without user to reload page every time. I'm ready to pay some bucks as well for such a mod. Thanks.
