Where it will come in handy is for very remote places, assuming it's cheaper than the other satellite IP systems in existence already like BGAN and Imarsat.
ITN did some lives from the Antarctic a while ago. No chance of using mobile networks there, or a geostationary satellite so used one of those systems which use low orbit satellites.
The thing that has made satellite cheaper and easier is VSAT - very small apparture terminal. These are small low powered dishes that connect to a central hub which manages them so they have lower requirements for licensing.
They're in use in lots of places such as shops and other premises that need a good fast connection. They're also installed in vehicles. So instead of a traditional SNG truck which requires a trained engineer to point the dish and monitor the transmission they can be operated automatically by a single technical operator. Often they'll be a one person crew - camera and uplink.
Most of the BBC regions have one of these for their regional news. BBC Local Radio stations use a VSAT system for their radio cars. They just turn up, press go and the dish moves and connects
Problem is that low power = small carrier = less bandwidth so for traditional MPEG video the quality isn't great sometimes. However using a bonded cellular system like LiveU or WMT to compress the video and then send it IP through that small carrier is a lot better quality
