Presta 1.5.x with Amazon S3 and Elastic Load Balance

[sibrodo]

I am thinking of combining my current presta installation (1.5.x) with Amazon S3 to store all static files (.js, css, images), so far this is the best tutorial i could find on the internet

How ever, it does not say anything about storing application state (e.g. cache), i am trying to have a single cache repository where all of my instance should get the cache from that location only. This way i can keep all of my instance in sync. Does anyone knows how to deal with presta cache, as far as i know presta cache is currently stored in the cache folder.
