I've had an idea for a while: some body (could be the government) maintains a list of useful/important infrastructure projects--bridges, hospitals, schools, etc. If you die with more than $x million, we take all the excess (like today's estate tax), but you get to pick what gets built, and have your name on it (or not, if you're like Feeney).
