D-Bus is not a good solution for machine-to-machine communcation, unless you 
patch D-Bus and you know what you're doing. If you're a beginner, then that's 
probably not for you.

nonce-tcp is a solution that requires the client to find a file, open it and 
read a shared secret which must be transmitted to the server. This ensures to 
the server that the client had the proper filesystem rights to find the file and 
read it.

By definition, this nonce file cannot be read by clients running on other 
machines, so remote connections would not be allowed.
