The idea is simple: hook up the little $200 box to your TiVo or your cable box and connect it to your home internet. Then, when you're out and about, just pull up the client software on your PDA or laptop. SlingBox's software will detect the quality and throughput of your connection and shoot you our a recompressed, digital stream of whatever analog signal you could be watching at home. It would even work on cellphones, they say, if the bandwidth were there (and it will be Real Soon Now).
