Viacom has enough clout to take stuff down from YouTube, but they probably won't care about this, much less threaten legal action. Universal tends to turn a blind eye to bootlegs, and that's what this would be classified as. That's why U2Torrents and U2Start are alive and thriving without Uni caring. U2Start has a very liberal copyright-policy; anything and everything except DVD rips can go up as bootlegs (for instance, their second ZooTV Syndey night is a Westwood One radio broadcast of the already-edited concert). U2Torrents has a policy very similar to Interference's; no official material is allowed, including bootlegs of concerts that have been released in part or in whole officially. They allow this type of thing all the time.
