Sorry if this is somewhat off-topic, but MP just published an email exchange he had with some SEC toadie who came enquiring after his MPEx customer records, specifically pertaining to Satoshi Dice.
Seems to provide confirmation of what many have suspected... that US SEC is coming after bitcoin securities.

Much like the comedy email exchange between the RIAA and the Pirate Bay 6-7 years back, this is a case of a US agency believing they have automatic worldwide jurisdiction.
Insisting on IRC/email was also smart - keep everything recorded in black & white, not 'lost' on some phone call.
