I am trying to sync website files uploaded to a windows 2000 FTP server to an Apache server.

The Apache is running Debian 4. I'd like to initiate file transfer from the Apache if I could.
I attempted to install Unison on the apache; and connect via ssh to the windows2000 server. At first I didn't realized I needed Unison to be running on the server. After it didn't work; I found that buried in the doc.

I believe I might have Unison working if I can get Unison to listen on the Win2000 FTP server, but I don't know how. Am I just asking for trouble with this setup?
Right now both servers are sitting next to each other on the same subnet on the same LAN. Would it be better to attempt an NFS mount on the Apache from the Win2000 server? If I did that; would it significantly hinder my options for moving the Apache to a remote site?
I heard development for Unison has all but stopped? Is this right? Other than Rsync, Is there any other options at all? Do you think there is a better solution for what I am trying to do? I don't think initiating transfers from the FTP server is a great idea; doesn't seem like it would scale well to a large environment. But if it comes down to it; I'll do whatever I need to do. Thanks!
