So I was thinking for my syncing software, it should be as simple as:

Setup:
1. `add` directory to IPFS
2. `files cp` directory to MFS
3. Generate IPNS key, associate with CID of directory in MFS

Updating:
1. Scan for updated files
2. `add` updated files to IPS
3. `files cp` updated files to directory on MFS, replacing already existing files
4. Using IPNS key generated at setup, associate with CID of directory in MFS

That should function correctly?
