Did you turn off peering or authentication?

Peering seems natural for the case where you have 2 equal servers and you 
want them to keep an eye on each other.  Aside from reducing the number of 
packets by a factor of 2, are there any reasons for using peer rather than 
server?  Is there any extra information exchanged?
