I think I understand what you mean.  Basically, you have an untrusted 
network shared drive and you want to store files on it that the server 
admin can't get to, right?

If you are using samba or NFS, it is as straightforward as following the 
directions I posted.  All you have to do is save the initial image file 
on the remote server.

For example, let's say that I have a samba mounted directory on my 
system.

	# smbmount //server/share /mnt/share -o username=ep,workgroup=foo
	Password:
	# cd /share

Now I just follow the directions as before, just making sure that the 
file I create with the dd command is created in this /share directory. 
The same thing applies to NFS.
