Personally I don't like to include more external libraries than needed, 
but if this is a special case for BSD I wouldn't care as much as I don't 
use this platform :)

I guess that BSD4/5 is missing functionality to "bind" a socket to a 
spesific interface like Linux can?
If this is the case, I don't understand what libnet does to fix this 
that olsrd cannot do directly?

If this is not the problem you are trying to fix, what problem does 
libnet fix for you?
