Indeed, seemed something has been missed (sorry for late reply). 
Can you try something above rv489 

debul-level 3 should show (batmand -c -d 3):
Adding route to 10.20.0.222/32 via 10.20.0.2 (table 65 - eth0:bat)
and 
ip route ls table 65
10.20.0.222 via 10.20.0.2 dev eth0  proto static

I also like the idea of dynamically changing some parameters but on the other 
hand, what are the negative side-effects of restarting a daemon ? 
 - A client connected to the daemon might temporary loose connection
 - Do you know others?

Even if such message-flooding ist not implemented I just thought of whether 
there exist some standardized formats to announce such services (maybe the 
community network markup language CNML idea) ?
