That sounds like a great project!

Isn't PubSub with XEP-248 (PubSub Collection Nodes) also tree based?

How about:

- - Use collection nodes for folders, and non-collection nodes for files
- - Folder collection nodes do not need to have any items
- - You can easily determine which node represents a folder and which is
a file by doing a disco#info on it and determine it's type, which is
either collection or leaf.
- - Every node has set pubsub#max_items to '1'
- - The item of a file node contains the data of the file (and maybe
some metadata)

Best,
Florian
