If you setup the complete broker <-> broker-agent functionality, the  
broker becomes quite powerful. The software design should be safe  
regarding privilege handling.

However, I personally prefer to have the broker on a machine where  
users won't get a login shell. It is just a gut feeling. In theory, it  
should be safe having the broker on X2Go Servers. But still...
