Have a look at http://movies.unibrain.org/
This is an FTP site wrapped in a standard header, footer and style sheet. The header and footer can be any valid HTML. If this is what your after, see http://httpd.apache.org/docs/mod/mod_autoindex.html
For my example,
.htaccess looks like
IndexIgnore robots.txt uptime.txt include scripts images style
IndexOptions DescriptionWidth=* NameWidth=*
IndexOptions +IconsAreLinks +SuppressColumnSorting +SuppressLastModified
IndexOrderDefault Ascending Size
AddDescription "US Government on how to stop ID Theft " IDTheftVideo.avi
....
There are two other files, HEADER.html which has my standard header, and README.html, which is a standard footer.
