Have a look at the dot_draw and txtinfo plugin. The first one (in combination 
with an external perl/php script) draws a graph of the network on the screen 
(could use some work with node distribution on the screen ^^), the other one 
outputs all linkcost values for every node in the network.

Maybe it might be a good idea to send a mail to PAtrick Gerber 
<(spam-protected)> (look for a mail with "qt" in the title on this list), he 
is working on a QT application that displays informations from the olsrd 
routing daemon.
