Q: If you were given a "Name your Price" type of offer, what would you ask for?

If you are really good at your field, and you have specialized software engineering skills which suddenly happen to be in demand and have many companies interested in you, what would you ask for?

I guess, what would be an offer given to you right that you can't refuse? (I am assuming base only, no bonus/stock options). Everybody has a price, what would be yours (realistically speaking).
