Yep, just like rapidshare.com . Amazing script named XtraFile (a.k.a. XtraUpload) allows users to select file, and upload it with progress bar (flash or ajax) after upload is finished it will display download/delete links so you can share your file with friends.

From admin panel, you control almost everything, you can set and sell premium user packages, limit free packages etc.

Last stable build is 1.5.6 - http://www.xtrafile.com/download.html
But after development of more then 7 months, Xtrafile founders made script opensource, moved to Smarty template engine and fixed bugs, its still nigtly build (and its better not to use on production servers) you can grab it here: http://xtrafile.com/svn/nightly.zip
