I agree with Void, there needs to be a good reason that the Soul Society has taken to doing this, beyond the whole stuff about Karakura town and whatnot. Sure, the Vizard were killed by a Quincy, which gave them cause to worry perhaps, but the Spirit Fragments need to play a part in the story, they need to somehow threaten the entirety of Soul Society to the extent that they MUST act upon the idea that they might fall into the wrong hands.

My own take on the idea would be that they'd make whomever possessed them capable of power sharing, they become a focus for all things spiritual around them and all manner of creatures are drawn to them. Around whomever carries a fragment the human world would change, new abilities would be born and anomalies might open up. These anomalies, building upon what Sei said, would be akin to.. naturally occuring Senkaimon, tears in the Dangai. I think these... Reiketsu Gates would be much more frequent in places where two bearers of fragments live close by.

This could go a long way in explaining the rifts that appeared in Harbinger. Tetsuo, Kohaku and Fiona all have Soul Fragments, and live very close to another another and are often together as they belong to the same organization. From what I can surmise from Void, the Reiketsu would essentially simultaneously attract and repel one another, each fragment wants to be whole again.. but at the same time, they each exert their power on the world around them, creating clashing bonds.

Anyway, when it concerns the Reiketsu Gates, they'd probably bring people potentially anywhere.. Yuanrang, Soul Society, Hueco Mundo, a random place on earth, sometimes thousands of miles away, others might bring passerbys a few districts away. Things of that nature, they'd probably also be visible to those with spiritual awareness. Like walls of blue mist.
