How to? AC Light Dimming w/ Labview (LIFA firmware)

My salutations to Arduino forum goers,

As the thread subject suggests, I was wondering if anybody has had any success obtaining AC light dimming capabilities with the Arduino talking to Labview via LIFA.

On the Arduino side of things I have decided to follow the solution suggested in this post: http://forum.arduino.cc/index.php/topic,106900.0.html.

On the contrary, I haven't quite figured out how to implement the code provided in the aforementioned post into LIFA firmware. In the following post: AC phase manipulated PID temperature controller via Arduino and Labview - Motors, Mechanics, Power and CNC - Arduino Forum the OP has basically done what I want to do except he's using a much older version of Arduino (with archaic libraries such as Messenger.h) and is not using LIFA to communicate Labview with Arduino. The OP also posted a video on youtube to help better illustrate his project:

As you can see from the first application he displays he is able to change the intensity of the AC load (radiation lamp) with Labview (which is precisely what I want to achieve).

Any recommendations on how to begin would be much appreciated!
