I couldn't disagree more, Fenris. The Great Ghost Dance and formation of the elf nations had nothing to do with the Matrix, as the nations formed as a result were both Matrix-connected.
The likely cure, and this is a bit of metagaming here, is to have the Resonance hold the solution. The reason why is simple: it gives the Technomancers the ability to be the "heroes" of the modern age. If there is a group of Technomancers out there - Denver Nexus, I'm looking at you - that could go into on really Deep Resonance quest to find the cure, it would be a huge shot in the arm for Technomancers everywhere. It would finally lend them a bit of legitimacy, while also confirming the fears of those who hate Technomancers. This could have the potential to really shift the power of the world, as the evidence uncovered in such a quest might implicate the corporate powers behind CFD. It would be a hell of a series of stories, and that's ultimately what we want here.
