Comcast will now let any of its customers use its Xfinity Share app, allowing many to live stream video to their home TVs or the TVs of other Comcast subscribers. Xfinity Share initially launched back in May, but at the time it was only available to people paying for a Triple Play package. Now anyone who subscribes to a Comcast service will be able to use the app. Unfortunately, the app's key feature — streaming to others' TVs — is limited by the fact that it only works on TVs that are connected to one of Comcast's X1 DVRs, so most people won't be able to receive a broadcast that way.

The app can also be used to stream video from one phone to another; although, at that point, you're basically just video chatting, and there are plenty of alternative apps that work with non-Comcast customers. The app is available on iOS and Android.
