As I understand it, a "chain" should not be possible. A deck has only so much processing power and if you would somehow split it over several devices, it should become slower and weaker.
But again, last call is with our beloved GM, and he seems to have quite an idea about how computers work, judging from how he provided a plausible solution for the Wrapper program(s). If that's possible, that would mean that you could practically slave an infinite number of devices to a single deck.
