Don't forget about Pla d'Adet, the cycling community training resort he was attempting to get large amounts of seed capital for in South Carolina. That project is on hold because of the real estate collapse, but it's still a very sound concept.
I still say if he mostly cooperates now, he'd potentially dodge a bullet. The comparison I see is Andy Pettit. He confessed to steroids and HGH, people frowned, but he seemed sincere, people forgave him, and he was back playing baseball.
But there's also indication that he's George is loyal to Lance, or thinks this won't affect him, and will try to play as Scribe says about "I don't remember", "I didn't see that". "That's not how I remember it". This would be a tricky line to walk, and if he's caught in contraction or ends up perjuring himself, he could come out looking like a liar or fool, have a lot of baggage to carry around, and it could take him years to recover from it.
I know what path I'd take, but I'm not exactly sure what path George will choose.
