I think the main issue to settle is why do you want to do this and what
sort of data will be transmitted. If you only want to do this once in a
while I could see using Telnet (actually, I would never use Telnet for
anything); however, if you want to routinely transfer data that you
wouldn't want others to sniff then set up a VPN instead. Or use the
Windows version of ssh which I believe is PuTTy.
