I have created a Scientific Linux 6.2 x86_64 Amazon EC2 machine image (AMI) and would welcome your feedback. The AMI currently resides in the us-east-1 (Northern Virginia) Amazon EC2 region. If there is enough interest, I could easily publish this AMI to all AWS regions. The AMI is ami-e2a0058b. https://console.aws.amazon.com/ec2/home?region=us-east-1#launchAmi=ami-e2a0058b Feel free to contact me directly with any questions/comments.
