As helpful as Sling TV might be for cutting the cord, its one-stream-at-a-time model has its limits. It rules out your family watching across multiple TVs, for instance, or (gasp) sharing with friends. Thankfully, the Dish-owned service isn't deaf to your requests: it's beta testing a $20 per month multi-stream option that lets up to three people watch at once. Besides giving you more freedom, the move also brings Fox channels that aren't available with a single stream, such as Fox Locals, Fox Sports and FX. You'll also get a few other channels that were either previously unavailable or limited to add-on packages, like Univision (normally an extra).
