No, it's not trivial to make extremely long time-based pieces on the web. Because you have to keep the computer running continuously. That turns out to be extremely difficult. So there is no spectacle, here. Part of the magic of Cage's piece, in this incarnation, is that someone actually built the special organ, in a suitable space that might plausibly remain undisturbed for several centuries. It requires some maintenance and some care and feeding, of course, but not much. So one doesn't have to suspend disbelief too much, here—this performance may actually occur as planned. It's been going for over 20 years so far, after all.
