Unless there are any showstoppers, this is the one that is going to the MySQL Expo next week, to be presented on Wednesday.
It allows one to view and manipulate Amazon's S3 storage service as tables and items by MySQL. You can keep your blobs or large varchars or truely huge datasets in S3, and then join the tables against your local ones.
If you're a MySQL geek, please download it, install it, try to crash it.
Feedback and bug reports are most welcome.
