Yes, we noticed a drop in bandwidth usage (of course) and also a faster user response time, especially our users in Asia Pacific where there Amazon CF has CDN nodes:

• United States
  1. Ashburn, VA
  2. Dallas/Fort Worth, TX
  3. Los Angeles, CA
  4. Miami, FL
  5. Newark, NJ
  6. Palo Alto, CA
  7. Seattle, WA
  8. St. Louis, MO
• Europe
  1. Amsterdam
  2. Dublin
  3. Frankfurt
  4. London
• Asia
  1. Hong Kong
  2. Tokyo

That is why I can safely push the avatars to visitors via SimpleCDN.

Whoooo, that is very nice! I like that feature very much. The issue we had (have) with SimpleCDN is that they do not have international nodes. We like the Amazon CF CDN because of their 8 CDN nodes in the US, 4 in Europe and 2 in Asia (and they continue to expand and add more). I would consider SimpleCDN if they had a global reach like CF.

(If I did it, I would change text to tell visitors that their new avatar would be active within five minutes, and have cron run rsync every five minutes to push the files out to the CDN.) Not ideal, of course.

Yes, there are plenty of command line tools to update Amazon S3 and sync the images between CF/S3 and the server. We currently don't do it, but might consider it in the future. I like the SimpleCDN method on pulling missing files from the original server. That is very nice. So, I'll take this up with Amazon CF.

Cheers.

We user RR for this.. Worked great.

Another alternative, of course, is to use mod_rewrite and 301 over to the CDN of your choice, and not bother with editing templates or adding RRs.

..... FWIW
