Yesterday I sucessfully implemented Amazon Cloudfront CDN service on my blog by using W3 total cache. Now all my pictures and blogs items have this address: http://dterteheexample.cloudfront.net/wp-content/uploads/2008/02/photo.jpg
Now I am getting paranoid about CDN... I mean. SEO is it ok to use a CDN service under a SEP prospective? What will happen when I will stop using such Amazon CDN service? Will Google penalize me if i use CDN or when I will stop using it?
Some guidelines or opinions are really welcomed!

I have seen businesses start using and switch cdn providers with no penalties from Google. The only time I've seen problems is when the images themselves are ranking in google image search and using cdn causes the urls to change.
I would suggest putting the cdn on your own subdomain or on a separate domain that you own: cdn.mysite.com or mysitecdn.com That way if you decide to switch cdn providers you still own all the urls and are not beholden to the cdn company.
FYI if all you're using CloudFront for is static files (js, css, jpg, etc) MaxCDN is WAY easier to use. I used CloudFront for a year or so, but finally looked at alternatives because it was so hard to manage my files.
Look into the differences between the two and I bet you'll switch too, I'm glad I made the switch. Easy stuff to manage my files now....
p.s. I have not noticed any increase or decrease in SE traffic as a result of using a CDN. However, I have seen an increase in site speed.
