AmiFTPd comes with BGui-Gui or MUI-Gui. I tested the MUI-version, as I
didn't get the BGui-version to work on the fly.
The test-version doesn't come with great docs, but after configuring an
anonymous user and giving him access to some partitions as virtual
file-systems, FTP-FS was able to mount his HOME and showed the partitions
as folder to browse through.
