Maybe the CLI should move to the glusterfs (without -server) package? I'm not 
sure how many common users there are, but for the occasional usage I have it 
would suit me :)

Well, it does not allow the client to execute any command as root, which is the 
case for using ssh. There is definitely no encryption or authentication at the 
moment :-/ The only restriction is that the source-port of the gluster command 
is < 1024, so the gluster command needs to be run as root. I'm not sure if there 
is an option to disable that.

I'm probably missing some details, but personally I'm not a big fan of giving 
out a root password or ssh-key. The code snippet did not show an option that 
would make it possible to use an other user and combine that with strict sudo 
rules (similar to https://bugzilla.redhat.com/show_bug.cgi?id=632851).
