The txtinfo offers the most information, but only in text format through a 
telnet like interface (see /lib/txtinfo in the OLSR repository).

The httpinfo does parts of it in HTTP form, but it has not got any 
maintainance for many years and would need to be redone in a proper way with 
the new http server interface in the development branch (/lib/httpinfo).

The dotdraw plugin is an interface to create a graph description that can be 
rendered with a good library (/lib/dotdraw, see olsr-topology-view.pl for a 
rendering script).

2) You can't break even.
3) You can't leave the game.
