Lazy Gallery Option

So I’ve got 4 kids and demanding parents who want to see every photo taken. My goal is to make this super simple. I’m a technical guy, so my ideal situation would be:

1. Use an EC2 micro image to host wordpress (done. easy)
2. Use my current process to get photos off camera and dump into a local directory on my Ubuntu server at home
3. Use a cron job to synch photos to an S3 bucket
4. Use a combination of plugins to auto-create a gallery on the wordpress site.

Its #4 that I need help with. I found Lazyest plugin which seems to cover most of it, but seems to require a subdirectory on the wordpress server. I don’t know how to point it at the S3 bucket instead.
