A small note: With LMCE you can mix and match your home automation equipment. You can have 95% of your home use Z-Wave, and for the last 5% use some X-10 stuff, where the X-10 disadvantages like speed are not that big of a deal. I, for one, started with X-10 in my home theater room, where speed is no issue. The rest of my home will receive either Z-Wave or X-10. A Z-Wave switch sends a command to LMCE. LMCE in turn switches on the X-10 light.
That's the beauty of LMCE.
