File sharing web script

[AZ Pete]

Hi All,

I have a need to be able to make large files to available to several 
clients for download.  When the need currently arises I use 
megaupload.com, which is a nice service for free, but I would rather 
keep things all on my server.

What I want to be able to do is to upload said huge file (200Mb-500Mb) 
to my web host via SSH/FTP. Then simply send my client a url where they 
can download that file via their browser.

Are there any apps that can do this? I did some searching on 
sourceforge, but couldn't really find anything.

Thanks,
Peter
