I have to agree. I have found this tutorial extremely helpful, but I felt as if the use of the context object was overly complex for what your aim is here. I think I spent about 1 hour total trying to figure out what it was for. When it he light bulb hit, I tried to simply return a value. After finding that this work, I felt like I wasted that time. Being able to pass an object reference in/out is helpful, but not needed to get your point across.

I really did like your tutorial - just not the communication part...
