For now, the potential of a jailbroken Apple TV is more exciting than the reality of a jailbroken Apple TV. Eventually, one hopes, it'll become an iPhone and iPad-friendly, internet and local-video playing swiss army knife. As of now, it's pretty much a $US99 Netflix set-top box.
But an easy jailbreak is a nice step down the path to the Super Apple TV, and that's just what Seas0nPass is. Developed by fireCore, the fellows behind the web browser-enabling and Last.FM-enabling aTV Flash suite, Seas0nPass will currently let you SSH into your Apple TV, run a buggy version of Plex, a slick piece of media streaming software, and and not a whole lot else. Yeah. But the jailbreak is open source and hopefully will bring about even more ATV tinkering.
