My 2 (late) cents:

P2P will, in my understanding, increase the need for partition tolerance, 
which will start hurting either availability (sounds bad, but it depends on 
your application needs) or consistency (sounds bad too, though it can be 
worked-around for applications only needing eventually-consistent, not 
consistent at every point of time).
