Xfire has a new feature that a person can broadcast live! I tried it out myself and no issues at all! here is the link to my broadcast page!

Not sure if all games work but I will be broadcasting when I play Guildwars. Can’t promise if I will broadcast every time I play but will attempt from time to time. If you have xfire and have me on your list you can see if i am broadcasting or not. The mini profile does not specify and unsure if that will ever will be added in the future. Feel free to leave comments about the gameplay! This is a public alpha version and anyone can use it. Willing to test out new technology. I love it!
