But if anybody in the Austin Convention Center was going to start a figurative fire, it would be Cuban and Ronen. Cuban, the owner of the Dallas Mavericks, escalated into the billionaire ranks after he sold Broadcast.com to Yahoo in one of the dot-com era's most famous billion-dollar deals that ultimately went nowhere. He has since founded the HDNet cable brand and become one of YouTube's (and free online video in general) harshest critics. Ronen's Boxee media center software has become one of the digital video industry's foremost enfants terrible, and Ronen's bull-in-a-china-shop attitude has made him a hero among geeks and an object of critique for pundits who say he'll never be able to ink the deals that Boxee needs to succeed.
