Well, because of a few requests, I've uploaded the whole lot them over to MediaFire.
metallidean_grl & dana_chosenart, this is for you. ;)
Until I can get Season 6 as BluRay downloads for capping (and who knows when that will be), these will have to do.
All 22 episodes are here and you'll find most are anywhere from 2 to 4 folders.
SPN S6 HD Caps
Happy downloading. Hopefully none of the folders will disappear, but if they do, let me know.
