Turbo trashed?

[spiffy926]

I finally got a chance to look into the oil consumption issues of my newly acquired 760. Sure enough, the compressor wheel has massive up and down movement. I've never seen anything like it, it moves probably a quarter inch.
Now I have to assume that the grinding type noises I heard a couple times on the drive home was the sound of the compressor wheel scraping on the sides of the turbo bore.
Should I even bother with a rebuild? Or should I assume that the turbo housing its self has sustained damage and just replace the whole thing?
Has anyone been so foolish to let a turbo get to this point? And had you been able to fix it?

I'll be pulling the turbo off the engine sometime in the coming weeks, and I'll be able to inspect the damage further.
