actually diploma thesis seem to be quite cheap nowadays ;-)
At funkfeuer we regularly have a few DAUs (duemmster anzunehmender user - 
most idiotic user you could image) who manages to misconfigure
his /etc/olsrd.conf. All that is needed is a Hna4 { 0.0.0.0 0.0.0.0 }
as far as I recall. So: we have lots of diploma thesises to offer :)))

Switching between evil and good: iptables .. -j DROP as already mentioned.

Another hopefully better idea for a simple diploma thesis:
make olsrd packets signed so that black holes cannot be intentionally forced.

Just my 2 cents,
aaron.
