The setup with RA2 is very simple. . 
You simply connect the main repeater to the MLGW. . .i think the new software in the
MLGW will recognize commands from the RA system.
I have the older MLGW software so I actually had to write my own commands. . 
However, I have RA2 Keypads for "CD,iTunes, Forward, Back" and the Fade buttons control volume up and down. . 
I simply told the RA2/MLGW softwares that when button 'X' is pressed do function 'Y'
It was very simple to arrange and I love it.
I have a 'party' button that arranges lights and turns on playlist 'red' on my BS5 throughout the link system. . 
Very nice product. . . 
Any specific questions just ask!
