Installing C* on EC2

[Mohit Anchlia]

What's the best way to install C*? Any good links?
Is it better to just create instances and install rpms on it first,
just like regular cluster and then create image from it? I am assuming
it's possible.
Are there any known issues when running C* on EC2?
How do other C* users deal with instance failures when using local
storage on EC2 since local storage is gone at that point? Launch new
instance and run repair?
