The document discusses using Python and FUSE (Filesystem in Userspace) to create simple filesystems. It provides examples of existing FUSE-based filesystems like redisfs and gmailfs. The FUSE API is outlined which Python can use to implement filesystem attributes and methods like getattr, rename, read, and write. The author's approach is to implement just the necessary methods for the task. Live examples are presented and questions from the audience are invited.
