ganjagadget's Journal: Streaming cable for the world to see?

I found a program called TVUplayer http://www.tvunetworks.com/. It allows me to watch TV channels that other people stream from there TV cards in a peer to peer way. It works very well and has local (SF Bay Area) channels plus a slue of other viewing choices, including Comedy Central, ESPN, and international channels like aljezira. But no one is brodcasting HBO. I am considering boing HBO my self instead of buying a sling box. Is this legal? If not why and how might they catch someone?
