Method to determine if transaction is a dependent on (tainted) transaction

[DBordello]

I am wondering if there are any tools that take two inputs:

1)  A list of transactions that you believe are tainted.  Aka, the recently stolen coins.
2)  Another transaction that you want to check to see if it contains tainted coins.

How are people verifying they are not receiving stolen coins?

PS. I am not trying to start a discussion about "tainted" coins.  I am just curious.

I guess that should be doable - however after 1 hop you have no chance of knowing if the coins are still "dirty", I doubt a lot of people would get that though.

If you really want to troll this system, steal a large amount of bitcoins and then send 1 Satoshi to _every_ address so far in the blockchain.
