Hey guys, glad I can finally post!  I "purchased" an X1 model from bitcoinminingcenter.com, Phoenix Technologies, on 11/13/13 through Coinbase transaction.  I have an email trail between myself and Xiao consisting of over 30 messages.  I have received this response from Coinbase:

"unfortunately they did not register any identifying information with us because they never bought or sold Bitcoin on our website. I can tell you that they funneled most of their Bitcoin offsite through the address '16hhF6FhbZiAcv6fyrXatnTqi1wFvzWtyt'."  (If you trace this address through the blockchain, you will see this douche made off with >940 BTC, 2.33 of which were mine!).

So, I am thinking there may be some options for US prosecution as well?  I am hoping at least...
