curious about the math of deal-making

[doormat]

I rarely play in tournaments and neither condemn nor endorse deal-making, but purely from a math standpoint I am curious as to the fairest way that players should split the prize money if they choose to make a deal. The simplest case would be 2 players remaining, one has 100k and the other 200k. Assuming equal skill, what would be the fair deal on splitting the prize money? How would it differ in NL from limit? What if there were 3 or more players involved? Forgive me if this is a trivial matter covered in tournament books, which I have not read.
