Bandwidth for these services is provided by LiveTV, a wholly-owned subsidiary of the carrier that provides the entire fleet with select DirecTV and XM radio channels, and which also happens to possess a valuable 1MHz slice of ground-to-air spectrum that it's deploying for this very purpose (with the help of some 100 existing cell towers around the country). If all goes well in what is admittedly a beta test, more aircraft will receive the WiFi makeover, and more features -- such as access to terabytes of locally-stored multimedia content -- will be rolled out, along with additional service providers besides Yahoo. Just don't expect an open pipe any time soon: that sweet little slice of spectrum is not nearly robust enough to handle the heavy Slinging, VoIPing, and Torrenting you all would obviously be doing.
