This might be OK for Unix-Unix transfers, but it's not great for transfers
of text files between Unix and non-Unix (e.g. Windows, VMS), and of course
it's not available for a lot of platforms where standard file-transfer and
security are available.
Other options include FTP secured by Kerberos IV, Kerberos V, SSL/TLS, or
other IETF-standard security method. I understand HP-UX 11 includes
K5 and SSL/TLS support. Whether that includes the FTP server and client
I don't know (does anybody?). Other FTP servers that include IETF-approved
authentication and encryption methods are listed here:

And your old friend C-Kermit (in its new 8.0 release) is a secure (and
scriptable) FTP client to these servers. Unlike scp, it handles platform
differences and doesn't assume everything is Unix. Not only can it convert
between Unix and other text-file formats, it also can convert text character
sets, e.g. HP-Roman8 / ISO Latin-1 / Unicode UTF-8:

And then there's Kermit protocol, which is in many ways more powerful and
flexible that FTP protocol, and these days also about as fast. Kermit
clients AND servers can be built with Kerberos IV, Kerberos V, SSL/TLS,
and/or SRP security:

C-Kermit can be a secure client of RFC2839/2840 Internet Kermit Service:
http://www.columbia.edu/kermit/cuiksd.html
or of any of the secure Telnet servers listed in the first reference above.
