Anyone try their hand at performing some arbitrage with bitcoin? Any success?
(specifically between mtgox and cavirtex)

The spread between exchanges seems favorable at times (over the fee %)

Anyone know of an automated solution for the aforementioned exchanges?

Thanks in advance.

Hi guys, anyone have any luck preordering any of the new bitforce miners from butterfly labs?

I've tried phoning them to setup a wire and prepay for some units - but I guess they are so swamped I've not gotten a call back.

Any thoughts?
