I tried to get sector working on a bunch of machines two weeks ago but it didn't work out.
I will get back to it when I have some more uninterrupted time though. I always love it when there is a tutorial on something, you follow it and it doesn't work :(
Check out Eucalyptus [open.eucalyptus.com/] It's compatible with amazon's EC2 and S3. The guide walked me through it. There was a hiccup but the forum helped me out in no time.
