I have a fully working automatic ubuntu image for sale to run mining instances on Amazon. At the moment the script uses ypool and automatically mines on startup with the cores available and restarts when the script is not running.
You don't want to pay the normal prices on Amazon; they are way too expensive to mine with. I can give you help how to use the Amazon cloud and how to buy instances with spot request, so you can buy the cloud vps's with spot instances yourself!
You only need to register an Amazon account and an ypool account. I will transfer the image to your personal account so it's fully yours at that moment.
If there is enough interest I can build the image for other pools.
please PM me if you're interested
