There is a good standard way to export files in a LAN with respecting unix permissions etc -
that is called samba.
However, I didn't find any nice way to do the same via WAN (i.e. via the Internet).
There are of course ways for us geeks - like sshfs.
But there is no really good way for "normal people".
As a protocol, webdav comes to my mind.
But actually, apache doesn't really sound like an application to run as root,
and also it doesn't really support transfering unix permissions.
So, any hints where to go to?
