On the director side, you could use bconsole. You can do that from a 
script, too.

On the fd side, you could write a ClientRunBeforeJob that creates a 
"flag" file somewhere (say, create a file called 
/var/run/baculaJobRunning), and a ClientRunAfterJob that removes it.

You can do the same thing on the director side, too, if the bconsole 
approach is too complex.
