Essentially, yes; however the twists are:

1. We plan to use HTTP form-based upload.  People are more likely to be
familiar with a web-based interface than FTP.

2. Users won't have accounts on the server (so no account maintenance is
required).  They won't have any direct access to the system other than
HTTP upload and download, and hence they should not be able to gain
access to other users' files without knowing the URL.
