There was an article about this in the Wall Street Journal yesterday. It said that the service would likely cost about $15 per hour, in contrast to the several dollars per minute air phone.
It's supposed to be broadband access, with 5Mb/second receive and 1.5MB/s transmit. On a full 777 with everyone doing some bandwidth intensive work, that might get slow, but for Web browsing and some streaming media, that's plenty fast, considering that not everyone is going to use it.
And, it looks like it's going to be via an ethernet connection, not wireless. So, each seat should theoretically have an Ethernet jack. Just like they all have power ports, right?
