Besides that... i agree it will be hard to get an escrow for that amount of money. It's fearsome to hold that much i imagine. And even established escrows might run since it might be that that amount of money is enough to throw their morals over board.
I disagree with this part. My personal integrity has no dollar limit to it. If someone offered me $1 billion, and had it, in cash, right now, asking me to do something I disagree with, it would affect nothing. I don't care if others could live with my decision -- I care that I wouldn't be able to. And to me, stealing by using someone's trust is the ultimate act of betrayal. I wouldn't even steal from someone I absolutely hate, much less someone I don't.
