I will admit, that I never tried STunnel with Peter's FTP server.
RSync should work with STunnel, but I haven't tried that either.
There is Open Private Network:
ftp://ftp.netlabs.org/pub/unixos2/openvpn.zip, which I have been meaning to check out, but I haven't done it yet. The package doesn't seem to have any documentation in it, other than what is displayed when you try to run it.
Another option, which is probably easier, is to simply copy your files to a USB thumb drive, and carry that with you.
but no clue if this is doable with stunnel or openssh.
Probably the easy way to find out, is to try it.
