This should be combined with routing table (i.e. how many nodes are
served by each tunnel), which is possibly redundant.
ip6tables should be avoided if possible.
U : Great !!!
U : Babel seems to be very long to establish the routes : maybe we should
tell him thant we are not on a wired network but on a mobile network ?

interfaces as wireless. However, treating an interface as wireless
doesn't lessen the hello_interval, it only changes how babel estimates
quality link, and cost.
U : from babel web page : "When the Babel daemon detects a wired network,
it will use a larger interval between hellos".
Moreover, it seems that the wireless option only means
"hostile environment" which seems best for a resilient network.
30 sec of hello interval seams also too much. The default value for
babel is 4 sec (from babel man page).
According to raphael's stats on the nexedi's server downtime,
most of the problems dont last more than 3 min. If it takes 2 min to
detect a dead connection, then we wont be solving anything with our
overlay network
Thimothée is making some stats about this for his internship. I will
commit them as soon as he as finished
U : The peer DB size should depend on the number of connection and the
refresh time
