Also, "scp" doesn't work with the "Windows®" clients, unless one wants 
to install Cygwin and OpenSSH (or a proprietary SSH implementation) on 
all of them.

Personally, I'd love to have a few optional (when enabled in 
bacula-fd.conf on the client) "utility" functions like this
in bacula-fd.  A simple no-authentication-required "yes, I am running 
correctly" response that can be triggered with a plain-text telnet 
connection, a similarly simple authentication-optional (depending on 
setting in bacula-fd.conf) telnet-inducible "bacula-fd version and 
status" response, and a simple operating-environment report (free disk 
space, free RAM, CPU usage) from bacula-fd would all be handy for 
troubleshooting and monitoring.  (That first one would be a lot more 
comforting than the current "well, I can connect, and it disconnects me 
when I type something, so maybe it's working" method of troubleshooting.)
