Secure FTP to/from WD My Book Live Duo Personal Cloud Storage device

There is a 4GB limitation when attempting to remotely transfer files (after mapping a drive using the wd2go.com website interface and java applet) from the WD My Book Live Duo Personal Cloud Storage device due to the limitations of WebDAV.  Granted you can enable FTP as a potential workaround, that is not a secure file transfer protocol and security of device logon information could be compromised as a result.  With Secure FTP capability, even though WebDAV is unusable for remote large file (>4gb) transfersyou could use a secure FTP protocol to transfer files in between the cloud storage unit and your laptop, PC, etc. to circumvent the limitations of WebDAV.  I am surprised that WD markets this product as being able to share and access your files from anywhere when that is not entirely true.  You can do so only if your files do not exceed the sized limitation of 4gb which, per my research, is not disclaimed in any documentation (user manual, product sheets, etc.) that I have thus far seen.
