It seems to be a special torrent client that work similar to tor (guessing with less hops though) and bounce encrypted traffic on special “i2p routers”. Not sure if they do the onion style encryption of thor.
No they’ve committed to keeping it. But they have an issue with port availability so they’ll probably need to move to a per server allocation eventually. Recently they reduced the allocation per user down to 5 from 20 though just to delay when they run out.
Hard to describe since it’s literally called livetv… It uses the saint martin top level domain… ymmv
Don’t download their player obviously
