Tonight was the first time that I've really dived into the www.be-at.tv site and I'm absolutely loving every minute of it. I have no clue how they are keeping this service free but it's a site that allows you watch live sets from the comfort of your own home. Tonight alone I was able to watch a recent set from Marcus Schossow (2nd part of his set was particularly strong), Paul Van Dyk's album launch party in Berlin, Chuckie's Memorial weekend set at Marquee in Vegas, Art Department, and finally Gareth Emery at Ministry of Sound.
You can follow the set by looking at the track listing at the bottom and skip to the parts you want to watch. I'm honestly blown away by be-at.tv and have felt like I've saved 10k in flight/hotel costs thanks to this site.
