kind of off topic (remote file access with Windows)

[Eric S. Johansson]

I know this is kind of off topic but since ubuntu is half of the 
problem... I mean solution, I thought I would ask.

I'm trying to access files on an ubuntu system that's "far away" (i.e. 
path obstructed by two firewalls and the Internet) I really don't want 
to do the file copy both ways because that's pretty error-prone.  From 
what I can tell my only solution is webdav but I was hoping for 
something a little more elegant and easily secured using ssh tunnels. 
shfs would be great but there's no Windows side filesystem connection. 
smb and nfs don't tunnel very well as far as I know.

So any ideas?
