My few cents: The current SWiM doesn't share when two receivers are tuned to the same transponder. The external SWiMs also have six inputs, so there is "some room" for more SATs. MoCA 2.0 wouldn't be a major change should DirecTV want to change. It uses 100 MHz BW and the splitters already are spec'd for 475-625 MHz. It is backward compatible too and ups the node limit to 32. As for the DSWM, if the current thoughts hold true, it's an evolution of the current SWiM, "but" will have more of a receiver so it can decode "a channel" from the transponder. This will then be encoded [modulated] onto an RF signal and become "a SWiM channel". Software in the receiver should be able to "fine tune" to these new frequencies, but "I doubt" we'll see 40 channels, if they're starting at 13, since this requires 13 tuners and encoders/modulators.
