I understand what it does. It just doesn't help much for wired devices
that send x10. It only helps for things you plug in, which are RF
transponders and PC/microcontrollers. So, to actually use the XTB, you
will end up moving all of the user inputs to RF so they can be relayed
through a transponder to the XTB. Wired transmitters such as light
switches won't benefit. Even if you pop open the XTB and wire it
in-line with a wired controller, you'd need one at every location you
want to put a controller, which would be expensive and difficult to
install.

So an XTB solution is really about eliminating x10 signals generated
directly from user input, and using RF instead.
