Yes, Tahoe-LAFS with a single storage server definitely is useful.
I've used this mode of operation in the backend of a custom file sharing
application I've built to help users who usually would have tried to
send huge attachments by email. Instead, the user connects to an HTTPS
web server, upload files and enters the email address of its recipient.
library to the Tahoe-LAFS WAPI for creating a new dirnode and uploading
files into it and then a CGI script transmits the read-only URL to this
dirnode by email.
