Penso che la risposta di Jon Ayers ci sveli un piccolo importante
particolare, la copio di seguito.
Dovremmo provvedere a compilare olsrd 0.6.7 su openWRT 14.07 e testare
questa feature.
Sono fermamente convinto che il carico computazione del parse di un
file di testo sia nettamente inferiore al carico di un processo che
usa DHT e fà node discovery in p2p.

In questa accezione a parità di beneficio ( sfruttando al massimo
nameservice ) avremo un carico - anche in termini di over head di rete
- nettamente inferiore.

We've been relying on this capability in our released image for a few
years and recently jumped from olsr 0.6.4 to 0.6.7 shortly after it
was released.  No experience with what might work or not in-between.
