Equinux, makers of iSale, CoverScout and an interesting collection of other apps, was at Macworld demoing TubeStick, their TV receiver. Like El Gato's EyeTV, the TubeStick is a hardware doohickey with the TV parts inside (logically) and some software that lets you watch TV on your Mac. Unlike El Gato, however, there is a social aspect to TubeStick. Example: you can chat with friends who are watching the same thing. The CEO took us on a quick tour, which you can view after the break.
(Note: Equinux also gave us some show swag which we'll be giving away next week)
