Simple.TV and the like

So really hits the sore spot that I've missed in the last six months since cutting the cable. All I have is the internet pipe and and OTA antennae for everything else ( as well as a Roku).

Simple question with probably a not so simple answer. Will be sued out of existence or is it probably good to go. I'm debating whether to back it on Kickstarter but don't want a doa product.
