I do only CPU Mining and my miner doesn't support X11 so I'm out.
I've had three machines mining for the last few days using Scrypt and didn't notice they weren't doing anything. I'd consider changing my miner but it is integrated into an app I wrote which switches from one coin to another every couple of hours so it's hard for my users to all change over.
I will look at the X11 option another time, but for the moment I've transferred my coins to the Web Wallet and will see what happens in the future.
I wish you all luck and hope it goes off big for you all.
