Drop a note to http://www.haystacksoftware.com/arq/ - I'll wager they will have an option to create "Glaciered Archives" of folders within a few months. The developer there has already expressed some interest, and suggested that Arq would lend itself to pointing at a folder and storing it off to a Glacier Archive (with all the caveats around 4 Hour delay, 24 Hour of Availability, Costs associated with restores, etc...)

[I'm the developer] I'm hoping storing the metadata in S3 and the actual file data in Glacier would work well. I'm still looking into it.

That's awesome news. Just being able to take a folder on my Drive, and say, "Archive this 5 Gigabytes of photos for the next 50 years" - and know it will cost me around $30 (and, as time goes on, likely less as the storage drops) and I won't have to worry (much) about it, will be a big win - even if you don't come up with an easy way of integrating with the normal S3 backups - I bet a lot of people will love that feature.
