Translation files on load balanced multiple instance site We have quite a large Craft based site that requires load balancing so there are often multiple instances of the site. 

The problem we are having is with the translation files. Because these are stored as files when you update them through the admin they are only updated on the site instance you are currently on. Obviously this isn't scalable. 

What would be the best solution to make these static translations scalable in this sort of environment? Move the translation files to an S3 bucket? (this would be ideal but have don't think this is possible) or move all translation fields to the database somehow? (what would be the best field type to store them as and where?) or is there some other solution?
Why not just check your site into a git or subversion repository, and when the translation files are updated, push them to the repo, and have the other servers pull the changes down?

You could even automate it with the various git hooks.
