I have written one but haven't posted it for obvious reasons. In Satoshi's case, it's vexed by the problem that it depends heavily on what datasets you have access to. For example, the California IP leak reduces Satoshi's anonymity to perhaps 2 or 3 bits... but only if you know the location/identity of everyone in California and also where that IP was assigned to at that time.
