Don,
It may still take some time for DirecTV to allow more than one Genie per home. The limitation was really the original SWM head that only supports 8 tuners and the Genie has 5 tuners. So you could not physically attach two Genies to this SWM head. (Yes, you could insert a SWM16 box, but that was more expense and additional cabling for DirecTV.) They have now introduced a SWM13 head that would support at least two Genies. So the ability to connect more receivers is there, but it will probably take some time for this new technology to roll out.
