I don't follow Spider-Man (or any comics, really). But I think this is an interesting idea.
Of course, being a comic, and since apparently Doc Ock has Peter's memories for whatever reason, there's more than enough material for Peter to somehow come back if this idea goes belly-up. Which, judging from this thread, it probably will.
[I never really understood why comic writers bother to kill off the heroes (Superman's "died" multiple times, hasn't he?). It probably made waves to first time, but after they come back to life... what's the point?]
