[lug] Making an HTTPS tunnel to an FTP server

[Glenn Murray]

Thanks to all who wrote.  I will look into OpenVPN as I would prefer
an open solution, and, time permitting look at some others.   I did
find a proprietary FTP server/client that does what I'm after at
www.crushftp.com.

For the curious, the HTTPS (as opposed to SSH, etc.) requirement comes
from some contractual obligations tied to HIPAA requirements.  They
would be hard to change.

Thanks again,
Glenn
