I've been mining LTC and depositing directly to my btc-e account, running the arb bot to find the most profitable path to BTC on btc-e then sending the BTC to gox to cash out for USD and take advantage of the price difference. It's a rather round-a-bout way of going about things but it works out pretty well.

Also I figured out if you put in a support request with btc-e and ask them to white list your IP address it will stop your bot from getting blocked and eliminate the need for the round robin script.

I would highly suggest anyone using their API to ask them to white list their IP address.
