Sling!

From Jason Snell - macworld.com:
Slingbox is a clever little $250 device that attaches to your TV set, cable box, satellite receiver, or TiVo, as well as your home broadband Internet connection. Once it’s installed, you are free to leave your home and go anywhere with a high-speed Internet connection — your office, a hotel room, a Wi-Fi-enabled cafe, wherever. When you get there, you open up your computer, launch the SlingPlayer application, and something crazy happens. Back at your house, SlingBox starts compressing the video coming out of your TV set-top box and streaming it to you. Yes, this means that you can now sit at work and have your local team’s baseball game playing in a window. Or that you can go on a business trip and still watch your favorite show, played back from your TiVo.

Slingbox even comes with a built-in infrared transmitter, so that you can change channels (or navigate through a TiVo’s menu system) remotely. Yes, if you’ve got a family member still at home, they might get a bit freaked out when the TiVo starts flipping channels under the control of someone 2500 miles away. But these sacrifices must be made in order for technology to continue marching on.

Right now SlingPlayer works on Windows PCs and is being rolled out for handheld devices running Windows Mobile. But last month, Sling Media announced that they’re working on a Mac version of SlingPlayer as well.
