not sure if this is the same thing, but i've seen something like this a few months ago. To connect to the interwebs, just select the "xfinitywifi" network to connect to, then sign in to xfinity account in the landing page! ..<p>..BUT<p>the connection <i>sucked</i> since the signal was from other units in my apt. building....
Like most people, I'm not normally a Comcast fan, but this is really interesting.<p>It's really convenient in San Francisco because I can almost always find a network to connect to, but I do wonder about security implications of having this feature enabled by default on my home router.
