Some caveats:

• The file list currently tracks directory views (via the template) but not yet file downloads, as that requires a Piwik plugin that isn’t final so I haven’t installed it, adding it should be trivial though.
• As requests are passed through PHP using mod_rewrite it will result in long running scripts on your server, which may upset your shared web hosting provider.
• Scripts are not yet excluded by rewrite rules! You won’t want to keep other scripts containing sensitive information in dirs under the path.
• Access to files and folders beginning with “.” will be blocked.
• It only works on Unices, not Windows servers as they don’t have the “file” command to get the MIME type.
• You’ll obviously need an Apache installation with mod_rewrite.

To install it, just copy index.php, .htaccess and .filelist/ to the directory where you store your files. You can get the script (without icons) from SVN.
