Great post!For the record I recommended using an anonymous gift CC and LibertyReserve (where you can sign up anonymously and also hide the sending address in any transaction for a very small fee). This automatically removes any trace of you except your IP and that is only on MTGox - the rest would be pure speculation on the part of LE with no tangible provability.I think the bigger worry (for sellers) is getting your funds out so they are untraceable. At the very least if you are depositing a ton of cash into a bank account (especially US - thank you Frank-Dodd) you will have the IRS kicking your door in for tax evasion. You can set up offshore credit cards that will accept both Liberty Reserve and Pecunix (if you want something gold-backed) and both of those services are anonymous.Pecunix is actually the better of the two since you can connect to and use it via Tor. It is also 100% anonymous and requires no ID or even a name to set up, just a highly secure set of numbers, passphrase and acces PINs. I know a few people who do business on their own online and they swear by Pecunix, although it's tough to find a BTC exchange that will take transfers from it.All in all, excellent post, and those are the only contributions I can really think to make. If you are generating new receiving addresses for each transaction on your BTC PC program, and running through a tumbler before PC and on the other side of SR, you should be just fine. All you have to worry about then is the tax parasites...
