I would never suggest DC power distribution...I was thinking along the lines 
of a conversion at the home panel to low voltage DC for use with more simply 
designed LED lighting.  I don't have first hand knowledge because I haven't 
been willing to make the leap, but have been told the power supplies built 
into the rear section of the LED replacement bulbs get very hot.  They do 
have the appearance of a heat sink.  Just thinking if that could be 
eliminated it would probably increase efficiency....of course all it might 
do is move the heat load to the garage...
