Looks really good but I'm pretty sure miners mining ETH will not migrate to a new pool when there are so many of it existing already but you may have a better chance by adding more coins that are not so popular and the pool might start attracting miners.
You're absolutely right. We have tried ETH before and it didn't work because we were not able to gather enough hashing power to find a block in a reasonable time. A group (BRMiners) made a request to recreate that pool, and we were told that 30+ GH/s would be available right at the very begining. Well, it never happened, not even close to it, and we intend to bring it down soon.
What other coins would you recommend?
