Folder shared over internet by multiple users

Question

We would like to setup a folder on a server where we would keep our documents.
This folder would be mapped to windows like a network drive where users can copy/paste documents. Thing is, this folder would not be on local network, it would be on a server which is accessible over internet.
We don't want dropbox or something like that...
We were thinking of webdav, but we were wondering if there is something better?

Summary:
-Folder accessible over internet by multiple users (username/password)
-Mapped as a network drive on windows xp
-No Dropbox, or dropbox variations, no FTP, no VPN

Question: Should we use WebDav or there is a better solution?

Thanks!

Answer 1

This use case is exactly what WebDAV excels at. I'd recommend going that way unless you want the added complexity of a proper Document management system (Alfresco, Sharepoint, etc.).
