Ingress adventure sync
Not for hatching eggs or anything POGO or HPWU.
Not for gathering XM, or getting the trekker badge. (But that might be good too)
I think if we enabled an adventure sync sort of feature, we might be able to get around more of the speedlock issues that some people are still reporting.
Those of you who want ingress to morph into PoGo can suggest some in-game reason to hatch XM eggs now, but that's not my idea.
